Question

find an equation that solves for n:
1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64
I know that each equation is multiplied by 1/2 but i'm not sure how to write that so it solves for n.

Answer 1

i have no idea what "solves for \(n\)" means
usually that means write \(n=\text{ exprssion}\)
you can write \(a_n=\frac{1}{2^{n-1}}\) however, although that solves for \(a_n\) not for \(n\)

Answer 2

thank you
