Question 2 • AZ-Common Core Algebra II B
An arithmetic sequence has a constant difference between consecutive terms. Here the differences are 7 − 5 = 2, 10 − 7 = 3, and 14 − 10 = 4, so they are not constant. A geometric sequence has a constant ratio, but the ratios 7/5, 10/7, and 14/10 are not all equal. Therefore, the sequence is neither arithmetic nor geometric, which is choice C.
