Answer: Choice D

Explanation:

We can verify this by noticing the ratio between adjacent terms is the same

  • term2/term1 = -16/4 = -4
  • term3/term2 = 64/(-16) = -4
  • term4/term3 = -256/64 = -4

The common ratio is -4. Each time we need a new term, multiply the previous term by -4. Example: -16*(-4) = 64.
