To determine which sequence is not an arithmetic sequence, we need to check if the difference between consecutive terms is constant. Here’s the detailed analysis of each sequence:

A. Differences: 5 − 2 = 3,  8 − 5 = 3,  11 − 8 = 3,  14 − 11 = 3

Analysis: The difference between consecutive terms is consistently 3. This sequence is an arithmetic sequence.

B. Differences: 7 − 4 = 3,  10 − 7 = 3,  13 − 10 = 3,  16 − 13 = 3

Analysis: The difference between consecutive terms is consistently 3. This sequence is an arithmetic sequence. ...
