Answer: The answer is C on edg.
Step-by-step explanation: I got it right
Find the difference between each number:
-24/4 = -6
144/-24 = -6
The next number is multiplied by -6
You have the first 4 terms
5th term = -864 x -6 = 5184
6th term = 5184 x -6 = -31,104
7th term = -31,104 x -6 = 186,624
8th term = 186,624 x -6 = -1,119,744
