Tell whether the sequence is arithmetic. If it is, what is the common difference? 10, 15, 21, 28, . . . (1 point) 1. yes; 5 2. 6 yes 3. 7 yes 4.no

Answer 1

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.
