If (8,m,20) are three consecutive terms of an arithmetic progression, what is (m)?

Answer and explanation

Correct answer: 14

For three consecutive terms of an arithmetic progression, the middle term is the average of the first and third terms. Thus, \(m=\frac{8+20}{2}=14\). Therefore, 14 is correct. If 12 or 15 is chosen, the common differences on the two sides will not be equal. Exam tip: for consecutive AP terms \(a,b,c\), use \(2b=a+c\).
