In an arithmetic progression, what does (a) usually represent?
Answer and explanation
Correct answer: First term
In the standard notation for an arithmetic progression, \(a\) denotes the first term and \(d\) denotes the common difference. Therefore, the correct answer is the first term. Option A is incorrect because the common difference is usually represented by \(d\). In exams, remember the roles of \(a\) and \(d\) in the formula \(a_n=a+(n-1)d\).
