If the sequence is geometric, find the common ratio. If the sequence is not geometric, say so.
-24, 9.6, 3.84, 1.536, 0.61
A) 2.5
B) -0.4
C) 0.4
D) 0.61

Question

Quizplus · Accepted Answer

The common ratio in a geometric sequence is found by dividing any term by the previous term. For this sequence, dividing the second term (9.6) by the first term (24) gives 0.4, and this ratio is consistent for all subsequent terms, confirming the sequence is geometric with a common ratio of 0.4.
