6 Coins Puzzle

A fun puzzle to try on your friends.

I looked at this problem a couple of days ago and after solving it, I decided to extend it by applying 2n coins over 2n + 1 spaces (n >=1) and discovered that the number of moves it would take appears to be n(n + 2) (or (n + 1)^2 -1 if you like). My problem now is trying to prove it. Although the proof is crying out for mathematical induction, I just cannot put my finger on the step which allows for this proof.

I can do it in one move. I turn the paper 180 degrees

Naughty! But hat's off to you. That's the sort of thinking that the great physicist Neils Bohr would have considered.
