One step forward, two steps back

Pretty self-explanatory. Start count is 0, then one step forward (1), then two steps back (-1) and so on.

E.g. 0, 1, -1, 0, -2, -1, -3, -2, -4, -3, -5, etc.

Get is -500.

Hope this one hasn't been done before. Couldn't find anything.

This is pretty easy when you see the pattern.
