If and it is true that does it follow that
Yes it is true for n=3 since, 4^n =64 and 7n^2 = 63
So yes it does followe the k+1 example is this correct?
Yes, that is "proof by induction". If a statement, depending on n, is true when n= 3, and, whenever it is true for n= k, it is also true that n= k+1.
