Multiple Choice

Find the nth term of the geometric sequence.
- $$a = 3 ; r = \left( \frac { 1 } { 3 } \right)$$

A) $a _ { n } = 3 \left( \frac { 1 } { 3 } \right) n$
B) $a _ { n } = 3 \left( - \frac { 1 } { 3 } \right) ^ { n - 1 }$
C) $a _ { n } = 3 \left( \frac { 1 } { 3 } \right) ^ { n - 1 }$
D) $a _ { n } = \frac { 1 } { 3 } ( 3 ) ^ { n - 1 }$
