Using the equation (n+1)(n+2), use mathematical induction to prove that this is divisible by 2.
Given: n=1
n=k+1

What were your efforts for the "n=1" step? What assumption did you make for the "n=k" step? How far have you gotten in the "n=k+1" step? Where are you having difficulty in the induction-proof process?

Please be complete. Thank you.

When you put "1" in for "n", what did you get? When you put "k" in for "n", what (assumption) expression did you get? When you put "k+1" in for "n", what expression did you get? How did you use the "k" expression in the "k+1" expression? Please show all your steps, so we can tell where you're needing hlep. Thanks!
