To determine which of the given sequences is an arithmetic sequence, we need to check if the difference between consecutive terms is constant. Here is the detailed analysis of each sequence:

A. Differences: 14 − 7 = 7,  28 − 14 = 14,  56 − 28 = 28,  112 − 56 = 561

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

B. Differences: 9 − 3 = 6,  27 − 9 = 18,  81 − 27 = 54,  243 − 81 = 162

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