Hmm. I have to think about this one

mathmale · Answer

Why not write out a couple of terms of "What is the third term of a sequence that has a first term of 3 and a common ratio of 3?"

mathmale · Answer

First term is 3.  What's the next term, and why?

mathmale · Answer

Yes.  If the first term is 3 and the common ratio is 3, then the next term is 9.  However, 9 is only the 2nd term; you must now find the 3rd term, using the fact that the common ratio, r, is 3.  Please do this now.
