Question

Write the first five terms of the sequence.Determine whether the sequence is arithmetic.If so,find the common difference.(Assume that n begins with 1. ) A_n = (-2)n

Quizplus · Accepted Answer

The sequence given by $A_n = (-2)^n$ is not arithmetic because the ratio between consecutive terms changes, not the difference. The first five terms are -2, 4, -8, 16, -32, which do not have a constant difference between them.
