- Show that if the statement 1+2+3+...+n=n(n+1)2+2 is assumed to be true for n=k, the same equation can be proved to be true for n=k+1. Explain why this does not prove that the statement is true for all positive integers. Is the statement true for all positive integers? Why?arrow_forwardShow that if the statement is assumed to be true for , then it can be proved to be true for . Is the statement true for all positive integers ? Why?arrow_forward
