$$a,ar,ar^2,ar^3,ar^4,...$$
$$2,2\times 3,2\times 3^2,2\times 3^3,2\times 3^4,...$$ is what this looks like
general term is $a_n=2\times 3^{n-1}$

As @satellite73 indicated , the first term will be

a1 = 2, and
the next ones will be 
a2=(a1)(3) = 6, 
a3=(a2)(3)= (a1)(3)^2= (2)(9) =18

an = (a1)(3)^(n-1) = (2)(3)^(n-1)
