Question

A geometric sequence is defined recursively by an = 12an-1. The first term of the sequence is 0.001. Which of the following is the explicit formula for the nth term of the sequence? A. 0.001 * 12n+1 B. 0.001 * 12n C. 0.001 * 12n-1 D. 12 * 0.001n-1 E. 12 * 0.001n

Answer 1

a1=.001
r=12
a1*r(n-1)=an
.001*12(n-1)=an
C
