They write it out the same way it's written on wikipedia (s = 1 - 1 + 1... = 1/2). I just didn't want to have to assign variables in an otherwise simple explanation...

EDIT: It mentions that this is not entirely appropriate on the wiki page, and goes on to do other proofs. Still, my attempt was first and foremost to explain why it's possible, and not to give a proof I can't understand.
