Question

To determine whether the sequence is arithmetic and find the common difference, consider the differences between consecutive terms:

Common Difference = Subsequent Term - Previous Term

Let’s calculate the differences:

1. -8.3 - (-5) = -8.3 + 5 = -3.3
2. -11.6 - (-8.3) = -11.6 + 8.3 = -3.3
3. -14.9 - (-11.6) = -14.9 + 11.6 = -3.3

Answer 1

The given sequence is arithmetic and the common difference is -3.3.

Step-by-step explanation:

The given question is related to arithmetic sequences and finding the common difference. To determine whether a sequence is arithmetic, we need to calculate the differences between consecutive terms. If the differences are constant, then the sequence is arithmetic. In this case, the differences (-3.3) between consecutive terms are the same, so the sequence is arithmetic. The common difference is -3.3.
