1. The problem statement, all variables and given/known data Wn = 2 + 3(1/2)^n 2. Relevant equations 3. The attempt at a solution I am confused, all I tried so far is writing out the first 5 terms, but all that was helping me to do is basically find the Sum to infinity... so what should I do to find the Sum to n terms? I know the 3(1/2)^n will be a g.p. , and the 2 makes it sort of an ap.
