Quizplus · Accepted Answer

In an arithmetic sequence, the difference between consecutive terms should be constant. However, in this sequence, the difference between each term is not constant. For example, the difference between the 2nd and 1st terms is 2, the difference between the 3rd and 2nd terms is 4, the difference between the 4th and 3rd terms is 8, and so on. Therefore, the sequence is not arithmetic.
