1. The problem statement, all variables and given/known data Its a series of triangles, the data table being n-# 1-1 2-3 3-6 4-10 5-15 I need a general equation in terms of n. 2. Relevant equations 3. The attempt at a solution I cant really find anything. The solution has to be non-recursive, and i can find a bunch of patterns, but all of them rely on the term before and after. AAAAAAAAAAAAAAAAAH.
