Which of the following sequences is an arithmetic progression?

Answer and explanation

Correct answer: (5,9,13,17,\ldots)

In an arithmetic progression, the difference between every pair of consecutive terms is constant. In option C, \(9-5=4\), \(13-9=4\), and \(17-13=4\). Hence, its common difference is \(4\), so it is an AP. In option B, the differences are \(3,5,7\), which are not equal. Exam tip: To identify an AP, quickly check consecutive differences.
