Homework Help: Discrete Math

Posted by Francesca on Monday, March 21, 2011 at 12:42pm.

Use mathematical induction to prove the truth of each of the following assertions for all n ≥1.

n³ + 5n is divisible by 6

I really do not understand this to much. This is what I have so far:

n = 1, 1³ - 5(1) = 6, which is divisible by 6

Then I really don't know how to go on from here. I appreciate any helpful replies. Thank you!
