How do i use induction(effectively) to prove that n! < nn for n ≥ 2 ?
let p(n): n! < nn for n ≥ 2.
we see that p(2) holds true.
now i prove it holds for p(n+1) right?

Once again, you have a posted a unclear requirement.

First, A1 and A2 are not rows, A1 and A2 are cells. I don't know what you mean by "A1 row" and "A2 row"
If you mean the cells A1 and A2, then you have another problem.
