Answer: TRUE
Step-by-step explanation:
An arithmetic sequence is a sequence in which the difference between each term (number) is a constant.
Given the sequence is {3, -6, -15, -24}
3 - (-6) = 9
-6 - (-15) = 9
-15 - (-24) = 9
As we can see from above, the difference between the given terms is all 9. Therefore, it is indeed an arithmetic sequence.
