which of the following is the beginning of an arithmetic sequence?

Answer:
b. 22, 28, 34, 40
Step-by-step explanation:
This is the only sequence with a common difference, hence the only arithmetic sequence: 22, 28, 34, 40 (common difference of 6).
___
When adjacent terms of the sequence have the same difference, the sequence is arithmetic. When adjacent terms have the same ratio, the sequence is geometric. (Only a non-zero constant sequence will be both.)
