Question

Determine whether the sequence is arithmetic, geometric, or neither, and justify your response.

Answer 1

9514 1404 393

Answer:

  geometric

Step-by-step explanation:

The signs of the terms alternate, so it cannot be an arithmetic sequence.

The ratios of terms are ...

  6/-3 = -12/6 = 24/-12 = -2

The terms have a constant ratio of -2, so the sequence is geometric.
