Is N^2 - 1 odd or even

It depends on on what number you plug in for N. If N is even, the answer is odd. If N is odd, the answer is even.

Step-by-step explanation:

What I did is plug in an even and odd number. I plugged in 3 as the odd number. This gets me 3^2 -1. 9-1+8. Therefore the answer is even.

If you plug in 2, you get 2^2 -1 which gives you 4-1+3. The answer here is even.

I MIGHT HAVE MISUNDERSTOOD THE QUESTION!

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
