In the sequence (16,20,24,28,\ldots), what is the value of (a+d)?

Answer and explanation

Correct answer: 20

In this AP, the first term is \(a=16\) and the common difference is \(d=20-16=4\). Therefore, \(a+d=16+4=20\), which is the second term of the AP. \(24\) is the third term, so it is not correct. Exam tip: \(a+d\) is always the second term of an AP.
