Answer: -8
Step-by-step explanation:
The jump from 24 to 16 is -8
The jump from 16 to 8 is also -8
Each time we need a new term, we add on -8 which is the common difference. So we'll add -8 to 0 to get 0 + (-8) = 0 - 8 = -8 as the next term.
If you wanted another term after that, then it would be -8 + (-8) = -8-8 = -16
Then the next term after that is -16+(-8) = -16-8 = -24, and so on.
