I don't see what your asking.  Something seems jumbled.
All I see is that your example keeps increasing by an amount that goes up by one each time.

Hi!

I have a recursive formula like this:

a0 = 0
a3 = 1
a4 = 3
a5 = 6
a6 = 10
an+1 = an + (n-1) n >= 3

I need to find a formula for this recursion and prove it by induction. How would i do this?
