What this topic asks you to be able to do
- apply the result for expanding (a + b)^n when n is any positive integer
- recognise when a sequence is an arithmetic progression and when it is a geometric progression
- apply the formula for the nth term of an arithmetic or geometric progression, and the one for the sum of its first n terms, when solving problems
- apply the condition for a geometric progression to converge, and, when it converges, use the formula for its sum to infinity
