You can put this solution on YOUR website! 36
1*1=1
1*2=2
2*2=4
4*3=12
12*3=36
36*3=108
The next number would be
108*4=432
and we'd multiply by 4 4times, then mover to 5.

Start with 1.
Use 1 as a multiplier of the previous term for the next 1 term.
1x1 = 1
Use 2 as a multiplier of the previous term for the next 2 terms.
1x2 = 2
2x2 = 4
Use 3 as a multiplier of the previous term for the next 3 terms.
4x3 = 12
12x3 = 36 <-- (that's the answer, but let's keep going a little more.)
36x3 = 108
Use 4 as a multiplier of the previous term for the next 4 terms.
108x4 = 432
432x4 = 1728
1728x4 = 6912
6912x4 = 27648
