My problem:
a↓1=2, a↓3=12
as for the people that know what Im talking about or who dont, my arrows mean the number after is shifted down to the bottom (picture it like a exponet on the bottom)
yeahhh... xD
so anywho I'm stuck on how to figure this out when I know the first and last number of the seqence. :/
If you could help, much would be appericated! thanks so much for your time ^^

A possible solution for a-sub-n is (n)*(n+1).
