Since I won't be teaching IGCSE from next year, I may as well give my revision notes to as many people as possible.

They contain guides for each topic including questions/answers.

Sir i need Sequence revision notes And plz find nth term of following: 1 2 4 8 16 ? Plz Thanx

in this sequemce there is a common ration of *2 so use the formula
a(r)^(n-1)
a=1st number=1
r= common ratio=2
so
1(2)^n-1
so
2^(n-1)

2n^2 +2n ?
12-4=8
24-12=12
12-8=4
a=4/2
a=2
b=8-3(2)
b=2
c=4-2-2
c=0
so 2n^2 +2n

I won't be able to help anyone else before the exam tomorrow. I hope my help over the past few weeks has been useful.

I'm sorry about any questions that I have not answered.

In post #489 I have given a link to my revision notes. And look out for my thread on 14th May where I will be posting solutions to Paper 42.

Goodbye and good luck
