To determine if the sequence is arithmetic, we need to check if there is a common difference between consecutive terms.
By subtracting each term from its previous term, we can see if we obtain a consistent difference:
12 - 19 = -7
5 - 12 = -7
-2 - 5 = -7
Since the difference between each successive pair of terms is consistently -7, we can conclude that the sequence is arithmetic.
Therefore, the answer is D) Yes; negative 7.
