A) $a _ { n } = 3 ( 3 ) ^ { n - 1 }$
B) $a _ { n } = 3 ( 3 ) ( n - 1 )$
C) $a _ { n } = 3 ^{n - 1} + 2$
D) $a _ { n } = 3 + 6 ( n - 1 )$

The general term of a geometric sequence is given by $a_n = a_1 \cdot r^{n-1}$, where $a_1$ is the first term and $r$ is the common ratio. Here, $a_1 = 3$ and $r = 3$, so $a_n = 3 \cdot 3^{n-1}$.
