This is an alternating addition series with repetition, in which a random number, 66, is interpolated as every third number.

Correct Option: A

This is an alternating addition series with repetition, in which a random number, 66, is interpolated as every third number. The regular series adds 2, then 3, then 2, and so on, with 66 repeated after each “add 2” step.
