Multiple Choice

Write a formula for the general term (the nth term) of the geometric sequence.
- $2 , \frac { 2 } { 5 } , \frac { 2 } { 25 } , \frac { 2 } { 125 } , \frac { 2 } { 625 } , \ldots$

A) $a _ { n } = 2 \left( \frac { 1 } { 5 } \right) ^ { n - 1 }$
B) $a _ { n } = 2 \left( \frac { 1 } { 5 } \right) ^ { n }$
C) $a _ { n } = 2 \left( \frac { 1 } { 5 } \right) ^ { n + 1 }$
D) $a _ { n } = 2 \left( \frac { 1 } { 25 } \right) ^{ n - 1}$
