What is the common difference in (7,7.5,8,8.5,\ldots)?

Answer and explanation

Correct answer: 0.5

The common difference of an AP is found by subtracting a term from the term immediately after it. Here, \(7.5-7=0.5\) and \(8-7.5=0.5\), so the common difference is \(0.5\). The value \(1\) is not the difference between consecutive terms. In exams, verify the difference using any two consecutive terms.
