`n^2-1` is divisible by 8, if n is

If n is an odd positive integer, show that (n^2-1) is divisible by 8.

If n is an odd positive integer, show that (n^2-1) is divisible by 8.

What would be the values of n for which n^(2)-1 is divisible by 8.

Prove the statement by the principle of mathematical induction : 3^(2n) - 1 is divisible by 8, for all natural number n.

If n is an odd positive integer,show that (n^(2)-1) is divisible by 8.

9^(n)-8^(n)-1 is divisible by 64 is

9^(n)-8^(n)-1 is divisible by 64 is

if n is an odd integer, then show that n^(2) - 1 is divisible by 8.
