What is the value of (a) in the sequence (11,14,17,20,\ldots)?
Answer and explanation
Correct answer: 11
In an arithmetic progression, the first term is generally denoted by \(a\). The first term of the given sequence is 11, so \(a=11\). The number 14 is the second term and 3 is the common difference, so neither is the value of \(a\). Exam tip: To find \(a\) in an AP, identify the first term of the sequence.
