[quote=pollardrho06;516247]Thanks for responding bjh.
Why are you taking the first term to be 1? What if it isn't 1? I'm not sure I see what you're trying to do here. What am I missing?[/quote
Iknew that 81 is 3^4 so Imade r=3 and a =1
Making the progression 1,3,9,27,81 but since 81 is the fourth side the other 3 are 3,9,27. Dig?
