That's not a series, that's a sequence. Also, you put absolute value bars over it so that every term would be equal to 1. This is the correct way to input it into Wolfram: http://www.wolframalpha.com/input/?i=sum+of+%28-1%29^n

Yes I know it was a sequence I didn't know how to do summation on WolframAlpha. The correct summation would be:
sum of (-1+1)^n
Which does diverge via geometrical multiplicity but not arithmetically. Since we are not talking about a coordinate vector or plane of any sort, the proof stands.
