Absolutely brilliant video with great examples! Loved the last harder / more challenging question! Plan to teach this tomorrow as a way to 'ease back in' my Year 11s - first lesson back! You have planned the Geometric Part of the lesson for me! Thanks and keep up the amaaazing work! (Kashif)
Amazing news I love that my channel is helping teachers plan their lessons! This is exactly how I teach it myself! Please do let me know if there are any other topics that you are interested in 😁👍🏼👍🏼
I have noticed that India has a very high standard of maths education. There have been many maths videos that I have wanted to watch but cannot as I don't speak Hindi! Greetings from the UK.
@@TheGCSEMathsTutor your the best hah have my test in 1/2 days lot to ask for is it possible you could give and exam resources links for practice papers or topic papers, other than maths genie. Thanks so much btw im doing aqa. Thanks again and take care!
you can tell it's a quadratic sequence because either the question itself will tell you or you'll find out when you realise the 2nd difference between each subsequent number in the sequence is the same
If it is quadratic, it will be multiplied, or divided by a specific number. We call that number the common ratio. The way to find the common ration is n2/n1 n2 is the second term n1 is the first term
Hello sir I have a question.For 3.44 the example you gave at the bottom said 1000 would be the first year however if you are given 1000 to start with how would that be the first year.Wouldnt 1030 be the first year or is this example only an example to give us an idea of how geometric sequences work?
Question I have a question. When finding the nth term expression on a geometric sequence,you know you put on a few questions number x number to the power of n-1. Why did you take away 1? And would this type of question come up in a Edexcel GCSE paper. And when we get the first formula eg on one of the questions 6x2 to the power of n-1 can that be our answer or do we have to simplify it. Many thanks
This formula is literally what he explains in the video. I do not think you will lose marks for this, tho you will lose marks for not simplifying like he explained in the vid. Hope this helps.
You should be grateful that he's a good teacher thats posting free videos to help us get better grades. The ads allow his videos to get some money from UA-cam. Learn to say thank you
If anyone would like to support the channel you can buy me a coffee here: www.buymeacoffee.com/gcsemathstutor Thank you for all of your support! 😁🙏🏼
For questions like at 7:14
I find it easier to just divide the first term by the common ratio.
So, 6/2 = 3
3 * 2^n
Done.

Thank you so much for keeping these going with all that is happening 🥰
James Chester I have said all the way through this that I will continue to teach you all no matter what! 😁🙏🏼
@@TheGCSEMathsTutor such a king
Pls can u make some videos for transition from gcse to a level maths
Thanks very much sir, you resolve our doubts sooo well
My absolute pleasure 😁🙏🏼
Thank you!! I am from India, so not preparing for the GCSE exam, but your videos have been very helpful for me.

@@magpiestudent9357life is hard gotta go with its flow
the day before my gcse paper 3 and i finally understand this
Good luck brother
Same
@@seni4164same, good luck brother
Got my paper 2 in 4 days.
hi sir, can i just ask about 8:53, do you have to be specifically asked to simpify it that much or do you have to do it by default? thanks
I love this, i was wondering what on earth is the formula about geometric sequence. now i know its compound interest
honestly your videos have helped me so much
I’m so glad to hear that! Keep up the great work 😁🙏🏼
very underrated your a legend. I hope your familiar with my account commenting on your yt vidoes by now haha!
so is this only for iGCSE or will it come up in the standard GCSE maths as well?
So glad this came up on my paper 3 exam today🎉🎉
at last i understood this !!!!!!!!!!!!! thank you
i think the final example at 6:55 might be wrong, because 75x5=375
Wish me luck my exams in 15 minutes 😭 (ocr btw)
A little bit of correction.
It must be 3,15,75,375. So it is not ending with 325 but 375, if we are using the common ratio: "times 5" .🙂
At 6:18 Do you always put it to the n-1?
I love your theme song❤
please make fiboccani sequence
but thanks so much for this!!!!!
Consider it done 😁👍🏼👍🏼

No problem! 😁🙏🏼
how do we see the difference of geometric sequences and quadratics
you can tell it's a quadratic sequence because either the question itself will tell you or you'll find out when you realise the 2nd difference between each subsequent number in the sequence is the same
How do we know if the question is supposed to be geometric?
If it is quadratic, it will be multiplied, or divided by a specific number. We call that number the common ratio.
The way to find the common ration is n2/n1
n2 is the second term
n1 is the first term
ik I’m late but @RiverHeigths meant ‘if it is geometric’.

How do you write it if the sequence was dividing?
If it was divide by 3 u would just write 1/3

It’s at 8:53
+1-1=0. n-1+1=n. 2^2 × 2^2=2^4. Knowing this u should be able to figure it out
Would I be penalised for just using the formula a_n=a(r)^n-1 to find the nth term instead of the compound interest method in the gcse?
This formula is literally what he explains in the video. I do not think you will lose marks for this, tho you will lose marks for not simplifying like he explained in the vid. Hope this helps.
Great video
❤thank you
one is wrong... 2 X 4^n could be written as 2^(2n+1)
Arithmetic Progression?
Can u please reduce the amount of ads waiting my time in life for no reason
Agreed 💯💯❤
