prove the product of 4 consecutive integers is always divisible by 24 using the principles of math induction. Could anyone help me on this one? Thanks in advance!Sure For induction we want to prove some statement P for all the integers. We need: P(1) to be true (or some base case) If P(k) => P(k+1) If the statement's truth for some integer k implies the truth for the next integer, then P is true for all the integers. Look at...
