1x2 = 2,
2x3 = 6,
6x4 = 24

Answer 2

Thank you so much! Was never good at math and am helping my grandchild! Again, thank you!

Answer 3

Is there a "rule" that applies to this?

Answer 4

You would have to define the "rule" recursively perhaps

A{n} = A{n-1} * A{n-2}

Answer 5

..... something like that lol

Answer 6

A{n} = A{n-1} * (A{n-1}+1) perhaps?

Answer 7

factorial

Answer 8

yeah, thats the term :)

Answer 9

\[a_n=n!\]
