Hi
I just can't figure out what the formula is for the following row of numbers....
1 1 2 6 24 120....
I know it's like this
1 2 3 4 5 6....
1 1 2 6 24 120...
1x1=1 1x2=2 2x3=6 and so on
But for some reason I can't find a formula for this....
Anyone able to help with this?

It looks like the factorial function.
0! = 1
1! = 1
2! = 2
3! = 6
4! = 24
5! = 120
Etc.

I don't get it. Totally my fault for dropping out of highschool math, of course.

3! = 1x2x3
4! = 1x2x3x4
5! = 1x2x3x4x5
and so forth.
