Is the sequence (8,13,18,23,\ldots) an arithmetic progression?

Answer and explanation

Correct answer: Yes, common difference is (5)

A sequence is an arithmetic progression when the same number is added to obtain each next term. That fixed number is called the common difference. It is enough to compare consecutive terms, but checking all displayed pairs makes the pattern clear and prevents confusing the first term with the difference.

Here, \(13-8=5\), \(18-13=5\), and \(23-18=5\). Every difference is equal, so the sequence is an arithmetic progression with common difference 5. Hence choice A is correct. Choice B gives the first term rather than the change between terms. Choices C and D are incorrect because the differences are equal and positive, showing that the terms increase regularly.
