A) $- 5 , - \frac { 5 } { 8 } , - \frac { 5 } { 64 } , - \frac { 5 } { 512 } , - \frac { 5 } { 4,096 }$
B) $1 , - 5 , - \frac { 5 } { 8 } , - \frac { 5 } { 64 } , - \frac { 5 } { 512 }$
C)-5, -40, -320, -2,560, -20,480
D)-5, 3, 11, 19, 27
E) $- \frac { 5 } { 8 } , - \frac { 5 } { 64 } , - \frac { 5 } { 512 } , - \frac { 5 } { 4,096 } , - \frac { 5 } { 32,768 }$

Quizplus · Accepted Answer

The sequence starts with $a_1 = -5$ and each subsequent term is obtained by multiplying the previous term by $r = \frac{1}{8}$. This results in the sequence $-5, -\frac{5}{8}, -\frac{5}{64}, -\frac{5}{512}, -\frac{5}{4096}$, which matches option A.
