If (a=2) and (d=5), what are the first three terms?

Answer and explanation

Correct answer: (2, 7, 12)

In an arithmetic progression, the first term is \(a=2\) and the common difference is \(d=5\). Add 5 successively: \(2\), \(2+5=7\), and \(7+5=12\). Therefore, the correct sequence is (2, 7, 12). Option A does not maintain a common difference of 5. Exam tip: start with the first term and add the common difference to obtain each next term.
