For n=0, we have


f(0)=3

for n=1, we have


\begin{gathered} f(1)=2f(0) \\ f(1)=2\cdot3=6 \end{gathered}

for n=2, we obtain


\begin{gathered} f(2)=2f(1) \\ f(2)=2\cdot6=12 \end{gathered}

for n=3, we have


\begin{gathered} f(3)=2f(2) \\ f(3)=2\cdot12=24 \end{gathered}

and so on. Then, the pattern is given by


\begin{gathered} f(n)=3\cdot2^n\text{ for n}\ge1 \\ \text{with f(0)=3} \end{gathered}

Lets check our formula.

When n=1, we have


f(1)=3\cdot2=6

when n=2, we have


f(2)=3\cdot2^2=3\cdot4=12

when n=3, we have


f(3)=3\cdot2^3=3\cdot8=24
