question 83

Multiple Choice

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

• A) \(a _ { n } = \left( \frac { 1 } { 8 } \right) ^ { 11 - 1 } - \frac { 1 } { 10 }\)
• B) \(a _ { n } = \frac { 1 } { 8 } - \frac { 1 } { 10 } ( n - 1 )\)
• C) \(a _ { n } = \frac { 1 } { 8 } \cdot 5 ^ { n - 1 }\)
• D) \(a _ { n } = \frac { 1 } { 8 } + \frac { 1 } { 5 } ( n - 1 )\)
