Write a formula to find the nth term of a geometric sequence -1/3,1/2,-3/4,9/8

Step-by-step explanation:

first term a = -1/3

Ratio r = 1/2÷ (-1/3) = 1/2 * (-3/1) =  -3/2

nth term = ar^(n-1)

=(-1/3)*(-3/2)^(n-1)

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)
