THANK YOU so much for that wonderful compliment...and students like you are a constant reminder why I love teaching and why my wife and I work so hard to keep this channel growing so please be sure to sub and share it with everyone...BAM!!!
nCr is for finding the number of ways you can have r successes from n trials. So if you wanted to find out how many ways (Combinations) you could have 4 successes out of 10 trials....10nCr4 which equals 210. If you want to find out how many pizzas you can make from 3 types of cheeses and 4 meat topping, assuming you must choose one of each...you just do 3 x 4 = 12
Hi. I watched your videos on sequences (arithmetic + geometric + sigmas), and I got an A on my test, something I've been struggling to get all year (I haven't gotten an A in a WHILE (in precalc)!!! It was a big deal). Thank you very much. I plan to watch more of your videos before I take my final exam. You teach very well.
VEKAproductions CONGRATULATIONS! That's a great accomplishment and something to be proud of...I'm glad I could be a part of it! Thanks for taking the time to study and choose my channel to learn from. I hope you will share your story and my channel with your teacher so they can suggest my channel as an additional study reference to all their other students:) Now go pass that final exam like BAM!!! and let us know how you did...then, enjoy your summer:)
Professor RobBob, once again this is an awesome video/lecture on the Introduction to Arithmetic Sequence. All students should recognize the pattern with the given information.

Thanks! And thank you for liking my videos...now it will be like having your own personal tutor:) I hope you enjoy learning math from Tarrou's Chalk Talk, and if so, please be sure to share my channel info with others:D
I used the variable k as my index variable in my sigma notation. I could have used n or any other variable for that matter...but I used k so that needs to be consistent through the sigma notation.

On the third example you used separate ace of one formulas for the top and bottom of the equation. Is it okay to do both the top and bottom of the fraction in one formula?
You know what's sad, I'm a college student and I'm getting a better education on precalculus and trigonometry from these 16 minute videos than my teachers 1 hour and 50 minute lectures, thank the lord for these videos.
The first value is given, so to get the second number in the sequence n=2 you only need to add once.... 2-1=1. n-1 is the number of times you repeatedly add.
I am studying for midterms in my Algebra 1 class and we have learned these two formulas as Recursive, and Explicit. Are there any major differences (ones that will change the answer) between Explicit (which is how you described it) and General formulas? Thanks for the amazing videos, i always come to your channel when I have study issues :)
+Potato Bear Basically yes, the one An formula uses the first term A1 and n to give you any number you desire in your sequence immediately. So if you want the 90th number you don't need to go through the previous 89 numbers.
It doesn't do anything. It's a notation to use the preceding value in the next equation, and once you get that value. That will be your new n-1 and you plug in that to get the next term in the sequence
Absolutely! You can move the terms around as long as the signs go with them:) Thanks for watching. By the way, time stamps with your question is very helpful.
Sir, can you solve this problem for me ? because I spend lots of time to solve this but I never get the proper solution to this. The sum of the first three terms of arithmetic sequence is 24. The 1st, 2nd and the 6th term of the arithmetic sequence is equal to the 1st 3 consecutive terms of geometric sequence. Find the 1st 6 consecutive terms of the arithmetic sequence.thank you :)
You are saying that we are continuing your series on sequence? Please number your videos so we don't need to hunt for the first, second, or nth, in a series. Please
You will find my videos organized in playlists if you go to the homepage of my channel or you can check out www.profrobbob.com Or even more specifically here www.profrobbob.com/pre-calculus/intro-to-sequences-arithmetic-geometric
You make me want to be a math teacher Mr. Tarrou. Your enthusiasm doesn't just make me want to do math, but it also brightens up my day!

Hi professor I am Iraqi my name is murtaza I really happy for you to this post. thank you
All ur Tutorial Videos (Algebra 1&2, Calculus 1&2) are Creditable Master Piece of Work!!!
Thumbs Up!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
THANKS for that great compliment and for taking the time to like, sub and study with my lessons! Please tell all your friends, classmates and teachers to watch and do the same to support these free educational channels:D
Why aren't you my teacher? You make everything so simple! Thank you for the help!
great work !!
i wish i had a teacher like you from the beginning..... well at least now i can learn at my own pace from your videos :)
Thanks a lot
On the third example you used separate ace of one formulas for the top and bottom of the equation. Is it okay to do both the top and bottom of the fraction in one formula?
You know what's sad, I'm a college student and I'm getting a better education on precalculus and trigonometry from these 16 minute videos than my teachers 1 hour and 50 minute lectures, thank the lord for these videos.
What you say that if order doesn't matter (for example how many combinations of topings on a pizza) you can use the nCn formula??
And also the general term- does it have to be memorized?
Do you have to write K in the nominator and the denominator of the formula, i dont understand your note when you wrote that you write N instead of K.
What does n-1 mean in the general term formula
The first value is given, so to get the second number in the sequence n=2 you only need to add once.... 2-1=1. n-1 is the number of times you repeatedly add.
I am studying for midterms in my Algebra 1 class and we have learned these two formulas as Recursive, and Explicit. Are there any major differences (ones that will change the answer) between Explicit (which is how you described it) and General formulas? Thanks for the amazing videos, i always come to your channel when I have study issues :)
How would you know if the common difference is a negative
NVM
Do they give you the An=An-1 formula or is that something you have to memorize???
Susanna Weir That will depend on the teacher. My students in PreCalculus have to memorize them.
THE BEST 👍💥

You are awesome! Thank you so much for making these videos. :D

At 11.56 doesnt the first number of sequence start -1/5 or was it -1/n. thanks
+Sharif Ahmed I hope you kept watching. I am handing the numerator and denominators separately to simplify the process.
thanks for your prompt response.
+Sharif Ahmed you're welcome...I'm not always that prompt:(
Thank you so much
You're welcome and THANK YOU for watching and subbing...please share this channel with everyone:D
Thank you for uploading it!
Thanks for watching...please sub and share too:D
so the general formula would represent all the terms using just a1??
+Potato Bear Basically yes, the one An formula uses the first term A1 and n to give you any number you desire in your sequence immediately. So if you want the 90th number you don't need to go through the previous 89 numbers.
ProfRobBob okie dokie thank you!! 🍳🍳
+Potato Bear You are welcome:)
You look a lot like Timothy Omundson, the guy who plays Lassie in the show Psych.
+Mads Waldron omg yes!
He looks like Mr. Bean.
what does the n-1 mean and do
+Marty Willliams The n means the nth term you are finding or using for. the a_n means the value of that nth term
It doesn't do anything. It's a notation to use the preceding value in the next equation, and once you get that value. That will be your new n-1 and you plug in that to get the next term in the sequence
prof. can it be an=17-3n?
Absolutely! You can move the terms around as long as the signs go with them:) Thanks for watching. By the way, time stamps with your question is very helpful.
+ProfRobBob how can you find a1 in a word problem prof
a1 is going to represent what is given in your word problem as an initial value... the first number in your sequence.
Sir, can you solve this problem for me ? because I spend lots of time to solve this but I never get the proper solution to this. The sum of the first three terms of arithmetic sequence is 24. The 1st, 2nd and the 6th term of the arithmetic sequence is equal to the 1st 3 consecutive terms of geometric sequence. Find the 1st 6 consecutive terms of the arithmetic sequence.thank you :)
