Find a General Term an for the Geometric Sequence $$a _ { 1 } = 5 , r = \frac { 5 } { 9 }$$

Multiple Choice

Find a general term an for the geometric sequence.
- $$a _ { 1 } = 5 , r = \frac { 5 } { 9 }$$

A) $a _ { n } = 5 + \frac { 1 } { 9 } ( n - 1 )$
B) $a _ { n } = 5 \cdot \left( \frac { 5 } { 9 } \right) ^ { 11 - 1 }$
C) $a _ { n } = 5 - \frac { 40 } { 9 } ( n - 1 )$
D) $a _ { n } = 5 ^ { n - 1 } - \frac { 40 } { 9 }$
