Answered by bobpursley
If you double it..

1,3,9,27
which is the sequence of 3^n, n=1,2,3,4,..

so you want half of that.
What is 3x3x3x3 for the next term, then take half.
Answered by Reiny
I noticed this pattern

1.5-.5 = 1
4.5-1.5 = 3
13.5 - 4.5 = 9

suggesting that the differences could be powers of 3, so the next difference is 27, then 81 etc.

try that.
