what are the next three terms in the arithmetic sequence -8.4, -7.2, -6.0

Answer 1

The common difference between each term is 1.2.

To find the next three terms, we need to add 1.2 to the last term (-6.0) three times:
-6.0 + 1.2 = -4.8
-4.8 + 1.2 = -3.6
-3.6 + 1.2 = -2.4

Therefore, the next three terms in the arithmetic sequence are -4.8, -3.6, -2.4.
