Find a General Term an for the Geometric Sequence $$a _ { 1 } = - \frac { 1 } { 8 } , r = 5$$

Find a general term an for the geometric sequence.
- $$a _ { 1 } = - \frac { 1 } { 8 } , r = 5$$

A) $a _ { n } = - \frac { 1 } { 8 } + \frac { 1 } { 10 } ( n - 1 )$
B) $a _ { n } = - \frac { 1 } { 8 } \cdot 5 ^ { n - 1 }$
C) $a _ { n } = \left( - \frac { 1 } { 8 } \right) ^ { n - 1 } + \frac { 1 } { 10 }$
D) $a _ { n } = - \frac { 1 } { 8 } + \frac { 1 } { 5 } ( n - 1 )$
