- $$a _ { 1 } = - \frac { 1 } { 8 } , r = 5$$

• 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) \(a _ { n } = - \frac { 1 } { 8 } + \frac { 1 } { 5 } ( n - 1 )\)
