Hi all,
I am so sorry I don't know whether to post this. I am revising Proof by mathematical induction Further maths using an Edexcel FP1 book. The following is from chapter 6 example 3. I know how to work Proof by mathematical induction it is part of the example that I don't understand.
I don't know how the series notation becomes to equal to the highlighted part.

The problem here is "r is a power" and I have not meant problems where r is a power and the book does not explain so much about that.
Thanks for the help.
