Finding the general term formula an = 2A (n-1) + 2 ^ n + 1 Please see that the + 1 at the back of the question is outside, not (n + 1), and the (n + 1) in front of it is a corner mark. a1=5

An = 2A (n-1) + 2 ^ n + 1a (n-1) = 2A (n-2) + 2 ^ (n-1) + 1: an-a (n-1) = 2 [a (n-1) - A (n-2)] + 2 ^ (n-1) let B (n-1) = an-a (n-1), B1 = a2-a1 = 10B (n-1) = 2B (n-2) + 2 ^ (n-1) divide by 2 ^ (n-1): B (n-1) / 2 ^ (n-1) = B (n-2) / 2 ^ (n-2) + 1bn / 2 ^ n = B1 / 2 + n-1 = n
