Is (3,6,9,12,\ldots) an arithmetic progression?

Answer and explanation

Correct answer: Yes, because the common difference is 3

Check the differences between consecutive terms: \(6-3=3\), \(9-6=3\), and \(12-9=3\). Since the difference is always 3, the sequence is an arithmetic progression with common difference 3. Therefore, A is wrong because the terms are increasing, and D is wrong because 6 and 12 are even. Exam tip: A sequence is an AP when the differences between consecutive terms are equal.
