Thanks, this helped a lot. I just could never get my head around this topic at all before, but after watching this, I understand. I need this for my important exams, and this will really help me. Great teaching.

First, thank you for you comment it is nice to get some feed back on my videos.

I have done videos for specific exam questions but I cant post the links in this comment so if you do a search such as "nth term gcse maths exam practice higher" or "nth term gcse maths exam practice foundation" in the search bar on my channel it will find the relevant videos, think i will add some links near the end of the video to aid people to find exam practice questions.

I was dreading revising this as I couldn't do it well the first time, but this has helped a lot, thanks! :)

Lauren cant reply to your comment but i will comment here, 1, 4, 9, 16, 25, ... are the square numbers which is what Quadratic sequences are all about.

Where do you get the 1, 4, 9, 16, 25 numbers from? (Sorry, haven't learnt this is school yet so im quite confused)

What about 2, 17, 40, 71, 110? My teacher said that the nth term isn't like 4n + 2 but 5n + 2 - 3n.

Thanks! Been looking for this quicker method for ages!. Great vid! You could do a vis about when there are common differences in Delta 3

Thanks Rawmaths! I`ve got the nth term of quadratic sequences just fine thanks to this video! Plus have you uploaded a video involving this topic where you go through Gcse practice questions for foundation and higher tier.

This video helped me remember how to do these questions really easy :D

[arocks]

yup i finally learned these sequences, before i had to do them with guess work, i can save tonnes of time now!

[rehanicu]

thanks for your reply but I am sorry to bother you again, but how did you come with this 1/2 squared

[nikkistump]

Thanks so much I didn't get this at all at first, still a bit shaky but I'm practising and getting better. Thanks!! 😃

[yikyeungoceansun]

Thank you very much!! Helped a lot for my homework :)

[BrightSmilz]

what if your sequence is 4, 10, 18, 28, 40 ? its asking me for an expression for the nth term.

[lewiscampbell]

How would you do the question
N squared + 2
What are the first 3 terms of the sequence?

This video helped me a lot btw
