Tell whether the sequence is arithmetic. If it is, what is the common difference? 19, 12, 5,%C2%A0 (1 point) Responses No No Yes;%C2%A0 Yes;%C2%A0 Image with alt text: one-seventh Yes; 7
No
To determine if the given sequence is arithmetic and find the common difference, we need to examine the differences between consecutive terms.
Looking at the given sequence: 19, 12, 5, ...
To find the difference between 12 and 19: 19 - 12 = 7
To find the difference between 5 and 12: 12 - 5 = 7
The differences between consecutive terms are the same, which is 7. This implies that the sequence is arithmetic, and the common difference is 7.
To determine if the given sequence is arithmetic, we need to check if there is a common difference between consecutive terms.
The given sequence is: 19, 12, 5, ...
To find the common difference, we can subtract each term from the previous term.
12 - 19 = -7
5 - 12 = -7
The difference between each consecutive term is -7. Since there is a constant difference between terms, the sequence is arithmetic.
Therefore, the common difference is -7.
