n-2, n, n+2

n-2 + n + n+2 = -30

3 n = -30

n=-10

so

-12 , -10, -8

=======================

n + n+1 + n+2 + n+3 = 26 etc

I get it but why do we do n-2?

The second one equals to 32

I did n-2 to get n in the middle so I would get a simple 3n on the left. I could just as well have used:

n + n+2 + n+4

or

n-4 + n-2 + n

Also notice that the fact that it is odd or even is not used. Luckily it comes out with n even.
