Multiple Choice

Write an expression for the nth term of the geometric sequence.Then find the indicated term.? $$a _ { 1 } = 4 , r = \frac { 1 } { 6 } , n = 10$$ ?

A) $a _ { n } = \left( \frac { 1 } { 2 } \right) ^ { n - 1 }$ , $\frac { 1 } { 2,519,424 }$
B) $a _ { n } = 4 \left( \frac { 1 } { 6 } \right) ^ { n - 1 }$ , $\frac { 1 } { 2,519,424 }$
C) $a _ { n } = 4 \left( \frac { 1 } { 6 } \right) ^ { n + 1 }$ , $\frac { 1 } { 2,519,424 }$
D) $a _ { n } = 6 \left( \frac { 1 } { 2 } \right) ^ { n + 1 }$ , $\frac { 1 } { 2,519,424 }$
E) $a _ { n } = \left( \frac { 1 } { 4 } \right) ^ { n - 1 }$ , $\frac { 1 } { 2,519,424 }$
