Geometric Progressions | iGCSE | Grade 6+ Series | GCSE Maths Tutor

A video revising the techniques and strategies for finding the nth term of geometric sequences.

This video is part of the Algebra module in GCSE maths, see my other videos below to continue with the series focussed on equations and sequences.

These are the calculators that I recommend 💎

These are the new revision guides I recommend 💡

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)

Thanks very much sir, you resolve our doubts sooo well

[nasarali]

Pls can u make some videos for transition from gcse to a level maths

[athenaenergyshine]

I love this, i was wondering what on earth is the formula about geometric sequence. now i know its compound interest

[kitkat_]

the day before my gcse paper 3 and i finally understand this

[RiverHeights]

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!! I am from India, so not preparing for the GCSE exam, but your videos have been very helpful for me.

[lauuudd]

honestly your videos have helped me so much

[mustafatarek]

very underrated your a legend. I hope your familiar with my account commenting on your yt vidoes by now haha!

[TediBSS]

so is this only for iGCSE or will it come up in the standard GCSE maths as well?

[skell]

So glad this came up on my paper 3 exam today🎉🎉

[anyonymous]

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

[HumeraJabeen-hv]

Wish me luck my exams in 15 minutes 😭 (ocr btw)

[_mishii]

i think the final example at 6:55 might be wrong, because 75x5=375

[shanejoy]

please make fiboccani sequence
but thanks so much for

[isabellahibah]

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?

[diegomandragora]

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" .🙂

[thestargamerw]

At 6:18 Do you always put it to the n-1?

[sissi]

How do we know if the question is supposed to be geometric?
