Hmm \[\frac{(1+4)^k  1  4}{4}\] Try to use the binomial expansion, the 1 would cancel, leaving only the factors of 4.

Use the binomial expansion \[(1+4)^k = \underbrace{\binom{k}{0}4^{0}1^{k}}_{\text{This is 1}} + \binom{k}{1}4^1 1^{k1} + \ldots + \binom{k}{k}4^k \] \[\frac{1 + \binom{k}{1}4^1 1^{k1} + \ldots + \binom{k}{k}4^k 1 4}{4}\]
