Question

What are the first four terms of the sequence represented by the expression n(n – 1) – 5?

Answer 1

The first third terms are n^2, -n, and -5. There is not fourth.

Explanation:
To solve this, we would first distribute n(n-1) by doing n x n - n x 1. That gives us n^2 - n. Now, we add back the -5 which would be n^2 - n - 5.

Answer 2

N^2
-1n
-5
I'm not sure about the 4th
