This is a Geometric Sequence. 3 is the common ratio. So: a(n) =3^n. The first term=3^1. Second term=3^2. Third term=3^3. Fourth term=3^4.........10th term=3^10........1000th term =3^1000.....and so on.

Isn't an exponential function different from a geometric sequence?  Or is an exponential function one type of geometric sequence?  I can't find the answer to this on the internet... they all dance around it.  Thanks to anyone for helping me understand this.
