If (48,42,q,30,\ldots) is an arithmetic progression, what is the value of (q)?

Answer and explanation

Correct answer: 36

In an arithmetic progression, the difference between consecutive terms is constant. Here, the common difference is \(d=42-48=-6\). Therefore, the third term is \(q=42+(-6)=36\). Checking further, \(36-6=30\), which matches the given next term. If 34 were chosen, the differences would be \(-6\) and then \(-8\), so it would not form an AP. Exam tip: For a missing-term question, verify the common difference using terms on both sides.
