Multiple Choice

Write a formula for the general term (the nth term) of the geometric sequence.
- $0.00009,0.0009,0.009,0.09 , \ldots$

A) $\mathrm { a } _ { \mathrm { n } } = 0.00009 ( 10 ) ^ { \mathrm { n } - 1 }$
B) $\mathrm { a } _ { \mathrm { n } } = 9 ( 0.1 ) ^ { \mathrm { n } }$
C) $a _ { n } = 9 ( 10 ) ^ { n }$
D) $\mathrm { a } _ { \mathrm { n } } = 0.0009 ( 10 ) ^ { \mathrm { n } - 1 }$
