  1. 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.

  2. 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.
