I have a discrepancy with the videos. number 4 is:

Suppose you want to prove that for every positive integer n, 3 is a factor of n3 + 14n. To construct the proof, you should first observe that 3 is a factor of which of the following numbers?

A6

B9

C15

D18

But in the video it shoes a systems question.

If you check the section under induction,

the first step tells you to show that the formula works for the first term. in other words for n=1.

hence, if you plug in 1 for n in the formula you’ll find out that the answer is 15.

please next time indicate who your algebra 2 teacher is

the videos do not correspond to your test, they correspond to the worksheet you got from your teacher two weeks ago
