Answer:

this sequence has no common ratio

Explanation:

The ratios of successive terms are ...

4/2 = 2

8/4 = 2

-16/8 = -2

32/-16 = -2

-64/32 = -2

2 is not the same as -2, so this sequence has no common ratio.

___

The sequence 2, -4, 8, -16, 32, -64 will have a common ratio of -2 using the same method to find it.
