(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Present Value question

I didn't really know where to post this. It's for an actuary class which eventually gets to applied statitistics, so I put it here. Anyways here it goes

The sum of the present value of 1 paid at the end of n periods and 1 paid at the end of 2n periods is 1. Find (1 +i)^2n.

The back of the book says the answer is 3/2 + sqrt(5)/2

I start with

1/(1+i)^n + 1/(1+i)^2n = 1

There are no given values for i and n. Anyone able to help?
