If (a=7) and (d=4), what is the second term?
Answer and explanation
Correct answer: 11
In an arithmetic progression, the second term is the sum of the first term and the common difference: \(a_2=a+d\). Thus, \(a_2=7+4=11\), so 11 is correct. The options 12 and 28 result from calculation or operation errors, while 3 comes from subtracting the common difference. Exam tip: for the second term, use \(a+d\) directly.
