To determine whether a sequence is arithmetic, we need to check if the difference between consecutive terms is constant. Let's calculate the differences:
nineteen eight negative three negative fourteen...
The differences between the terms are:
8 - 19 = -11
-3 - 8 = -11
-14 - (-3) = -11
Since the differences between consecutive terms are all the same (-11), the sequence is arithmetic. The common difference is -11.
