Answer and explanation
Correct answer: 3
In an arithmetic progression, the common difference is the difference between two consecutive terms. Thus, \(d=5-2=3\), so option D is correct. Option A is the first term, while option B is the next term. Exam tip: use \(d=a_2-a_1\) for two consecutive terms.
