Re: What is the Next #??

Hello!

n^(n-3)

So for n=1 it'll be ...... 1^(1-3) --> 1^(-2) = 1
          n=2..................2^(2-3) --> 2^(-1) = 0.5
          n=3..................3^(3-3) --> 3^0 = 1
         n=4...................4^(4-3) --> 4^1 = 4
          n=5..................5^(5-3) --> 5^2 = 25
          n=6..................6^(6-3) --> 6^3 = 216
