Morning/afternoon/evening all,

I'm aware of the formula: a(r^{n}-1/r-1).

However, for the following:

100(1.01)(1.01^{n}-1/1.01-1)

Apparently (Mathematics for Economics and Business - Ian Jacques), this is the same as:

10,100(1.01^{n}-1)

Is that correct? I can't find out how to get to this.

Your help is always appreciated.
