The first term of a Geometric Progression(G.P) is 3 and the fifth term is 48. Find the common ratio

The nth term of a geometric progression is $a×r^{n-1}$. You are told that the first term $a = a_1$ is 3 and the fifth term $a_5$ of the geometric sequence is $48$. This means that $3×r^4 = 48, r^4=16$ and the common ratio $r = 2$.
