Try another version of this question Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
Find the nth term of the geometric sequence whose initial term is `a_1 = 0.5 `
and common ratio is ` 9 `.
`a_n = `
(Your answer must be a function of ` n`.)
Be sure your variables match those in the question `0.5 * (9)^(n-1)`
