To determine if the sequence is arithmetic, we need to check if there is a constant difference between consecutive terms.
Let's find the difference between each term:
15 - 10 = 5
21 - 15 = 6
28 - 21 = 7
We can see that the differences are not constant, as they are 5, 6, and 7. Therefore, the sequence is not arithmetic.
The correct answer is D. No.
