Answer and explanation

Correct answer: The difference between consecutive terms is constant

From 15 to 18, 18 to 21, and 21 to 24, the increase is 3 each time. A constant difference identifies an AP. A “three times” rule would describe a geometric pattern. In exams, compare consecutive differences first.
