To determine if the sequence is arithmetic, we need to check if there is a consistent difference between each term.
The first term is 10, and the second term is 15. The difference between these two terms is 15 - 10 = 5.
The second term is 15, and the third term is 21. The difference between these two terms is 21 - 15 = 6.
The third term is 21, and the fourth term is 28. The difference between these two terms is 28 - 21 = 7.
The differences between consecutive terms are not the same, so the sequence is not arithmetic.
The correct answer is 4. no.
