4chan, i require your assistance:
prove that 2^n+(-1)^(n+1) for n>=2 is always divisible by 3.
Any pointers on where to start? I know your not going to do my homework for me, this isn't actually the homework question, but if i can prove this then it proves what im trying to prove. Just some tips maybe ? thanks.
