Types of Sequences - GCSE Maths

[@minoo3157]

You actually did it, thank you sir ❤

[@1stClassMaths]

Of course! I said it was on the list, I am just working through :)

[@KrishBeeltah]

Hello sir could please do a video on Locus and mesuration✔

[@saeshashinde4279]

my math checkpoints are today and this video was helpful for revision thank you so much!

[@1stClassMaths]

Hope it went ok.

[@101adnap]

Can you make a video for percentage growth and decay I’m struggling with it a lot and simple and compound interest

[@hafzah_14]

If you go on first class maths on google you press GCSEs revision (your examboard) then you can find your topic

[@abreshmi_muskan]

I found it VERY useful. Thanks ❤

[@1stClassMaths]

You're welcome 😊

Will you make a video explaining how to get the nth term of geometric sequence .

[@1stClassMaths]

You don't need to know this for GCSE, only how to generate more terms. It is covered more explicitly at A-level. That said it isn't too tricky. Each geometric sequence has a first term, which we give the letter "a". It also has a common ratio "r", which is what you multiply each term by to get the next term. You can find "r" by dividing a term by the previous term. E.g. if the sequence is 3, 6, 12, 24, 48, ... a = 3 as it is the first term r = 2 as 6/3 = 2, or 12/6 = 2, or 24/12 = 2 etc. The nth term is this a * r^(n-1) so in this example 3 * 2^(n-1) Hope that helps but I will cover A-Level content in the future.

thanks :D

Sir could you plz do all of algebra and geometry foundation tier

[@1stClassMaths]

I am working my way through all the foundation topics don't worry.

[@rays.9621]

hello i have a question. So you cannot create formula for the nth termin both geometric and quadratic sequence ?

[@1stClassMaths]

You can. I have a video on nth term of quadratics sequences here: kzbin.info/www/bejne/bXrWkmeGbdF8icU The nth term of a geometric sequence is beyond the GCSE course however.

[@muyupo]

On the exam questions answer sheet, I think you've answered for the 5th terms instead of the 4th on questions 10 & 11.

[@1stClassMaths]

Thanks it was a typo. On the AQA one I put 5th but forgot to copy over. It is fixed now.

[@Sam26907]

thanks for your videos, I got an 8 in maths

[@1stClassMaths]

Amazing well done!

[@ExtraExtra-v2c]

Can someone please tell whether Fibonacci sequence is included in the IGCSE syllabus

[@1stClassMaths]

I don't believe it is.

[@ExtraExtra-v2c]

@@1stClassMaths thanks a lot!!!!

[@sajjadahmed1794]

​@ExtraExtra-v2c fibonacci sequences are included for o level igcse (for may June 2025 atleast)

[@ShafqatInam-gi8cv]

My all confusion is far away
