Question

I could really use some help

Find the next three terms of the sequence -8, 24, -72 , 216

A -648, 1944, 5832
B 648, -1944, 5832
C 248, -616, 248
D 216, -648, 1944

Answer 1

Answer: None of the above are correct

Step-by-step explanation: The values are being multiplied by -3 each time. (-8*-3=24, 24*-3=-72, and so on.) Out of all the choices, A would be the most accurate answer. But the problem is that 1944 multiplied by -3 does NOT equal 5832. It equals NEGATIVE 5832. As I said, A would be your best choice.

Answer 2

The sequence is increasing by the previous number multiplied by negative 3       (x -3). With this information, the correct answer would be A. -648, 1944, 5832
