A child reads (3) more pages each day. If (5) pages are read on the first day, what will be the sequence?
Answer and explanation
Correct answer: \(5, 8, 11, 14, \ldots\)
The number of pages read on the first day is the first term, so \(a=5\). Since 3 more pages are read each day, the common difference is \(d=3\). Thus the terms are \(5, 5+3=8, 8+3=11, 11+3=14\). Option B has first term 3, so it is not correct. Exam tip: In an AP, first identify the first term and the fixed change between consecutive terms.
