If (-6,s,10,18) are consecutive terms of an arithmetic progression, what will (s) be?
Answer and explanation
Correct answer: 2
The common difference between consecutive terms is constant. Here, the difference between 10 and 18 is \(18-10=8\). Therefore, the term immediately before 10 is \(10-8=2\), so \(s=2\). Check: in \(-6,2,10,18\), 8 is added each time. Exam tip: first find the common difference using two known adjacent terms near the missing term.
