- $$\frac { 64 } { 5 } , 8,5 , \frac { 25 } { 8 }$$

A) $a _ { n } = \frac { 64 } { 5 } \left( \frac { 5 } { 8 } \right) ^ { n }$
B) $a _ { n } = 64 \left( \frac { 1 } { 8 } \right) ^ { n - 1 }$
C) $a _ { n } = 8 ^ { n }$
D) $a _ { n } = \frac { 64 } { 5 } \left( \frac { 5 } { 8 } \right) ^ { n - 1 }$
