Answer: A

Step-by-step explanation: An arithmetic sequence is a pattern in which the same number is repeatedly added or subtracted.

Notice that in the the first sequence shown, we add 4 to reach the next term in the sequence which means this is arithmetic.

The others are not arithmetic because the difference

between the terms does not remain constant.
