How to find a formula for the nth term in a linear sequence, check the formula, and how to find other terms in the sequence; here we find the 10th term.
Tysm!!!! It really helped me out!! :) I was struggling to understand this topic, and I have an exam in 3 days. I can't thank you enough. You've got yourself a new sub. =D
Thankyou so much I have a test tomorrow and I needed to know this and you made it a lot easier. Do you have any tips for remembering all of this so I won’t forget it in the test.
It might help to look at an example where the terms are increasing: ua-cam.com/video/VgBSzYBMbh4/v-deo.html Then you can try to make up your own examples to test yourself...you could start with a formula, work out the terms, then see if you can work out the formula. Good luck!
finally i have found the perfect video, very clearly explained and will definitely be subscribing as this has helped me a lot, thank you for the great video!
But how about numbers that are decreasing by dividing 2 each num, for example: 2000,1000,500,250 and so on. How to write the algebraic expression for sequence like this?
This is actually the recursive method. If you want to do it the other way try using this formula: a₁ + (n - 1)d With a₁ being the first term, n being the nth place in the sequence, and d as the difference.
Thank you. Millions of people all over the world have been made happier for your existence👍
Thank you so much!
Very helpful I’m doing this topic in school thanks 😊
You're welcome 😊
@@MathsWithJay hello i wanted to ask wat if the its-5 if the valueminused keep increasing or decreasing? like -5 to -6 or -5 to -3
Simple and straight forward. Just what I needed💕
Thank you Constance
Thank you, you literally helped me pass my assessments
Happy to help!
Thank you for making this video it helped me a lot with my school work.
You're very welcome!
thanks for this i couldnt find any other videos for decreasing sequences and ive always struggled on nth term, this really helped :)
You're very welcome!
Watched this before my end or year examinations, and MY GOOD MAY GOD BLESS YOU. THANK U SO MICH!!! And now i subbed
Glad it helped!
Thank you so much! I have a test tomorrow and I completely forgot so this really helped
Good luck!! Great to know that this was useful
quite useful,i have been looking for these types of vid.

THANKSSS end of year assessments have me stressing you’ve just taught me and hour lesson in three minutes
Glad to have helped...good luck!
please I love this so much, I have a test soon and I am not prepared at all. This really helped, tysm!! Idk what I would’ve done without this
Good luck!!
THANK YOU SO MUCH YOU HELPED ME WITH MY MATHS HOMEWORK!😊
You are so welcome!
Thanks a lot! Having a test tommorow about this and having zero knowledge before watching this video. IM READY!
Best of luck!
@@MathsWithJay hi! The test got a bit tricky when it Said about nsquared stuff
Ah - see ua-cam.com/video/pSMxx4w547I/v-deo.html for nth term when n is squared
@@MathsWithJay omg tysm!
all the support to your brilliant videos
Big thanks
thank you so so much for this I really needed this for a homework ! just subscribed as well :)
Yay! Thank you!

Very easy method 👍 amazing
Thank you!
thank so much for the explanation it helped😊
You're welcome 😊
your videos are really helpful ❤❤
Thank you!
Thank you so much. I understand it fully after trying to figure this out for a full year
@Chumile Mtingi: A FULL year! Wow!
Thanks for helping. My maths teacher isn't even in school so we have to learn by ourselves and I didn't understand this topic at all.
You're very welcome!
My module brought me here ! 🤧 This really help me so thnks
You're very welcome!
I'm a grade 10 student and when I say you save me for this sy, I really mean it !! tysm

You taught me this in 4 minutes and my teacher couldn’t do it in 3 weeks
3 weeks?!
What is a way to rewrite the formula into a more general one?
@janneth aguirre: This is an arithmetic sequence, with first term a, difference d, so the nth term is a + (n - 1)d,
@@MathsWithJay is d the common difference?
@Dominic Castillo: Yes!
Thank you so much
Welcome 😊
thank you . Very efficient
@Mohamed Mehraz Jaleel: Thank you!
Thanks a bunch😅
Welcome!
THANK YOUUUU
You're welcome
Im watching this during the exam ty
During?
Tahnk u so much
Most welcome 😊
How about 4, 8, 16, 32 instead of adding them they've been multiplied by 2
This is not a linear sequence like the one in the video...your sequence will need an index (or power)
Thank you so much this helped a lot
You're welcome!
i got it right👏🏾👏🏾
Excellent!
this is perfect! thank you !
You're welcome!!
Woah! this seems so easy for me now :) thanks
its really hard for me before i watched this vid and now I was like "how would I think that way??!!" lol
@Xu Shiny: You're welcome 😊
@@MathsWithJay it's not common to see a youtube that likes every comments :) Your vids are so awesome! :)
...some comments are deleted and some people are blocked if their comments are not appropriate...
@@MathsWithJay True
This so useful, you deserve a like
@LilAndy TV: Thank you!
But how about numbers that are decreasing by dividing 2 each num, for example: 2000,1000,500,250 and so on. How to write the algebraic expression for sequence like this?
That's a geometric sequence
thanksss
Thank you
uhmm can i suggest a video where its decreasing but theres no common difference if thats alright sir thx for vid
Can you give an example?
thank you
You're welcome
Wait so its just like positive numbers?
@nene n: It's like an increasing sequence as in: ua-cam.com/video/VgBSzYBMbh4/v-deo.html
oh what if we use nth term= a+(n-1)d
Yes....that will work....a is the first term and d the common difference
Thx
Any time
how did the -3 come from i think its between 301-298
@lawmi thangluah1: 298 - 301 and 295 - 298,...
What if it goes to the negatives? Like 15, 7, -1, -9...
The same rule applies...what do you get for your formula?
@@MathsWithJay t = 23 - 8n!
how did u get the check n=2?
By substituting 2 for n
My mind is sleeping right now but where did you get the x again i can't understand BTW thanks😍😍
At what time in the video?...ua-cam.com/video/VgBSzYBMbh4/v-deo.html may be useful
@@MathsWithJay thnx bro
How to find the nth term of 9 2 2 -2 its confusing as it jumps from -4 to -3 and again -4. How do we write this in n terms
That is a baffling problem!
Would 304 - 3n also be a formula?
Try it: what do you get when you substitute n=1, 2,...?
@@MathsWithJay It worked for me. Thanks a lot!!!
what should i do if the numbers are, 123,113,93,83?
So no 103?
@@MathsWithJay no
This is actually the recursive method. If you want to do it the other way try using this formula:
a₁ + (n - 1)d
With a₁ being the first term, n being the nth place in the sequence, and d as the difference.
Or just a for the first term
@@MathsWithJay yup
how do you got the 2
At what time in the video?
50/50 for me but I’m just gonna plug it in and hope it makes sense lol
Another example might help: ua-cam.com/video/VgBSzYBMbh4/v-deo.html
I’m in yr8 and because of covid I missed it thanks
You're welcome!
what if the number sequence is a fraction?
This method works for fractions too if the differences are all the same
ok but what about when the sequence isnt linear?
ua-cam.com/video/pSMxx4w547I/v-deo.html has a non linear example
Why do we add three?
At what time in the video?
What if it’s like -12, -9, -6, -3, 0?
How do you think the formula will start?
Maths with Jay I actually figured it out thanks for the video
I FEEL LIKE EINSTEIN NOW
Wow!
Hello!
Hi!
I was filpen mind blown
:)
Why do you minus 6 when your checking
Because we're checking n=2, so 3n=6
WOAH that was wayyyyyy easier than i thought.
Great!
What about non linear decreasing sequences
@Dontay: ua-cam.com/video/5iLAGcz4Vfk/v-deo.html is a decreasing quadratic sequence
what if it goes 9 16 25 36 49 ?
See ua-cam.com/video/pSMxx4w547I/v-deo.html
How about this one
80,40,20,10?
See ua-cam.com/video/ggO5aKoopDw/v-deo.html
@@MathsWithJay thank u very much
useful - thanks
@letti Thank you!
cant it be -3n +304
Yes, but we prefer to avoid starting an expression with a negative
