Homework Help: Algebra 2

Posted by Chelsey on Saturday, November 17, 2007 at 8:07pm.

Write an equation for the nth term of the geometric sequence: -12,4,-4/3

I had a_n=-12(3)^(n-1) but that is not a choice on the multiple answers

they have = -12(1/3)^(n-1)
= 12(-1/3)^(n-1)
= -12(-1/3)^(-n+1)
= -12 (-1/3)^(n-1)
