D) - 3
E) not geometric

Question

Quizplus · Accepted Answer

The sequence is not geometric because there is no common ratio between consecutive terms. Typically in a geometric sequence, each term is obtained after multiplying the previous one by a constant factor, which is not the case for this sequence.
