To determine which sequence is an arithmetic sequence, let's define an arithmetic sequence. An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.

A. Differences: 4 − 2 = 2, 8 − 4 = 4, 16 − 8 = 8, 32 − 16 = 16

Analysis: The differences are increasing rather than remaining constant. This sequence is not arithmetic.

B. Differences: 10 − 5 = 5, 20 − 10 = 10, 30 − 20 = 10, 40 − 30 = 10

Analysis: The differences are not constant; the first difference is 5, and the others are 10. This sequence...
