(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Put in general terms 1, 1, -1, -1, 1, 1, -1, -1, ...

2. Relevant equations

3. The attempt at a solution

obviously (-1)^n, alternates 1, -1, 1, -1...

I have no idea how to figure this out. I thought it might have a sin function in it possibly.

Thanks a lot for your help.
