Question

A1=3 and a8= -6561
find:a6

Answer 1

-4920.75 or 18

Explanation:

I'm not quite sure if this is correct because I got two diffrent soultions for a.

In a1=3 I got a=3

In a8= -6561 I got a= -820.125

So i plugged my two solutions in to find a6

I got

18

or

-4920.75

That doesn't really seem correct, but I tried!!
