Provide an appropriate response.
-Let $f ( x ) = 3 \left( 2 ^ { x } \right)$, and consider the sequence $f ( 1 ) , f ( 2 ) , f ( 3 ) , \ldots$. Is this a geometric sequence, and if so, what is the common ratio?
A) Yes; $x$
B) Yes; 3
C) No
D) Yes; 2

The sequence is a geometric sequence because each term is obtained by multiplying the previous term by a constant. The common ratio is 2, as each term is obtained by multiplying the previous term by $2^1 = 2$.
