- Problem Statement
- Suppose that An (from n = 0 to inf.) = {1/1, 3/1, 3/4, 9/4, 9/16, 27/16, 27/64, 81/64...} where we start with 1 and then alternate between multiplying by 3 and 1/4. Find the sum of An from n = 0 to n = inf.

- Relevant Equations
- Sn = A0(1-r)/(1-r) iff |r| < 1

A0 = 1

A1 = 3

3(An-1) / 4(An-2) = An

A1 = 3

3(An-1) / 4(An-2) = An
