Is the sequence arithmetic? If so, identify the common difference. 15, 22, 35, 46, …

1 answer

Yes, the given sequence is arithmetic.

The common difference can be found by subtracting any two consecutive terms.

For example,

- The common difference between the first two terms is 22 - 15 = 7.
- The common difference between the second and third terms is 35 - 22 = 13.
- The common difference between the third and fourth terms is 46 - 35 = 11.

Since the common differences obtained are different, it can be assumed that the sequence is not arithmetic.
