Find a General Term A_n for the Geometric Sequence $$a _ { 1 } = \frac { 1 } { 7 } , r = 6$$

Multiple Choice

Find a general term a_n for the geometric sequence.
- $$a _ { 1 } = \frac { 1 } { 7 } , r = 6$$

A) $a _ { n } = \frac { 1 } { 7 } \cdot 6 ^ { n - 1 }$
B) $a _ { n } = \frac { 1 } { 7 } - \frac { 5 } { 42 } ( n - 1 )$
C) $a _ { n } = \left( \frac { 1 } { 7 } \right) ^ { n - 1 } - \frac { 5 } { 42 }$
D) $a _ { n } = \frac { 1 } { 7 } + \frac { 1 } { 6 } ( n - 1 )$
