Find a General Term an for the Geometric Sequence $$a _ { 1 } = - \frac { 1 } { 6 } , r = 4$$

Find a general term an for the geometric sequence.
- $$a _ { 1 } = - \frac { 1 } { 6 } , r = 4$$

A) $a _ { n } = - \frac { 1 } { 6 } \cdot 4 ^ { n - 1 }$
B) $a _ { n } = - \frac { 1 } { 6 } + \frac { 1 } { 8 } ( n - 1 )$
C) $\mathrm { a } _ { \mathrm { n } } = - \frac { 1 } { 6 } + \frac { 1 } { 4 } ( \mathrm { n } - 1 )$
D) $a _ { n } = \left( - \frac { 1 } { 6 } \right) ^ { 11 - 1 } + \frac { 1 } { 8 }$
