Answer:

#-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#
