Answer and step-by-step explanation:
To identify if the given sequence is geometric or not, let's find the common ratio by dividing each term by the previous term.
-2, 6, -18, 48
6 ÷ (-2) = -3
-18 ÷ 6 = -3
48 ÷ (-18) = -8/3
*Observe that one of the answer is different from the others. There is no common ratio if they do not have the same answers or quotients.
*A geometric sequence must have a common ratio.
Therefore, the given sequence is not a geometric sequence.
