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
To determine whether the given sequence is arithmetic, we need to check if there is a common difference between each term.
Let's calculate the differences between consecutive terms:
15 - 10 = 5
21 - 15 = 6
28 - 21 = 7
As we can see, the differences are not consistent. The difference changes from 5 to 6, then to 7, indicating that the sequence is not arithmetic.
Therefore, the correct answer is option 4. no.
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.
To determine if the given sequence is arithmetic and to find the common difference, we need to check if the difference between consecutive terms remains constant.
In this case, we calculate the differences between consecutive terms:
15 - 10 = 5
21 - 15 = 6
28 - 21 = 7
Since the differences are not constant, we can conclude that the sequence is not arithmetic. Therefore, the correct answer is 4. no.
