Answer:
The common ratio of the sequence is -2.
Step-by-step explanation:
=8
=±2
To know whether it is + or - 2
if we try positive 2:
8 x 2 = 16 ( here we can see that positive 2 is not the common ratio because the answer should be -16)
then try -2:
8 x (-2) = -16 ✔️
(-16) x (-2) = 32 ✔️
Therefore, -2 is the common ratio.
