Question 13

Multiple Choice

Find the nth term of the geometric sequence.
- 2,1,12,14,182,1 , \frac { 1 } { 2 } , \frac { 1 } { 4 } , \frac { 1 } { 8 }


A) an=2(12) n+1a _ { n } = 2 \cdot \left( \frac { 1 } { 2 } \right) ^ { n + 1 }
B) an=2(14) n1a _ { n } = 2 \cdot \left( \frac { 1 } { 4 } \right) ^ { n - 1 }
C) an=2(12) n1a _ { n } = 2 \cdot \left( \frac { 1 } { 2 } \right) ^ { n - 1 }
D) an=2(12) na _ { n } = 2 \cdot \left( \frac { 1 } { 2 } \right) ^ { n }
