If (a=2.5) and (d=1.5), what is the second term?
Answer and explanation
Correct answer: 4.0
In an arithmetic progression, the second term is obtained by adding the common difference to the first term: \(a+d=2.5+1.5=4.0\). Therefore, 4.0 is correct. The value 3.5 would result from adding only 1 to 2.5, not the given common difference of 1.5. Exam tip: For the second term of an AP, use \(a+d\) directly.
