Which sequence is not an arithmetic progression?

Answer and explanation

Correct answer: 2, 5, 9, 14, …

An arithmetic progression is defined by a constant common difference between consecutive terms. Test each option systematically. In A, the differences are 11-7 = 4, 15-11 = 4, and 19-15 = 4, so it is an AP. In B, the differences are -3, -3, and -3, so it is also an AP, even though it decreases. In C, the differences are 2, 2, and 2, so it qualifies. In D, the differences are 5-2 = 3, 9-5 = 4, and 14-9 = 5; they change from one step to the next. Hence D is not an arithmetic progression, and option D is correct.
