-4 is being added after each term to get the next term in the sequence.

Explanation:

"Arithmetic means" means that a constant number is being added again and again to create a sequence.

Let "the number" = n

We know that n is negative because the numbers in the sequence are getting more negative.

n=((-24)-(-8))/4
(The denominator of 4 comes from the 4 times a number has to be added)

n=(-16)/4

n=-4
