Select the First Five Terms of the Sequence $$a _ { n } = \left( - \frac { 1 } { 3 } \right) ^ { n }$$

Select the first five terms of the sequence.(Assume that n begins with 1. ) ​ $$a _ { n } = \left( - \frac { 1 } { 3 } \right) ^ { n }$$ ​

A) $- \frac { 1 } { 3 } , \frac { 1 } { 9 } , - \frac { 1 } { 27 } , \frac { 1 } { 81 } , - \frac { 1 } { 243 }$
B) $$- \frac { 1 } { 3 } , - \frac { 1 } { 6 } , \frac { 1 } { 27 } , \frac { 1 } { 12 } , - \frac { 1 } { 243 }$$
C) $$- \frac { 1 } { 3 } , \frac { 1 } { 6 } , - \frac { 1 } { 9 } , \frac { 1 } { 27 } , - \frac { 1 } { 15 }$$
D) $\frac { 1 } { 3 } , - \frac { 1 } { 6 } , \frac { 1 } { 9 } , - \frac { 1 } { 12 } , \frac { 1 } { 15 }$
E) $- \frac { 1 } { 3 } , \frac { 1 } { 9 } , - \frac { 1 } { 9 } , \frac { 1 } { 81 } , - \frac { 1 } { 15 }$
