Answered by GPT 3.5
The sequence is not arithmetic because there is no constant difference between consecutive terms.

To illustrate this, let's calculate the differences between consecutive terms:

7 - 3 = 4
12 - 7 = 5
18 - 12 = 6

As we can see, the differences are not constant. Therefore, the sequence is not arithmetic and does not have a common difference.
