Question

Is the sequence arithmetic? If so, find the common difference.

‒2.4, 6.4, 15.2, 24

Answer 1

i believe it’s the common difference is 8.8

Answer 2

Answer:

yes

Step-by-step explanation:

There is a common difference d between consecutive terms in the sequence, that is

d = 6.4 - (- 2.4) = 15.2 - 6.4 = 24 - 15.2 = 8.8

Since there is a common difference between terms the sequence is arithmetic.
