If (a=3.5) and (d=2.5), what is the second term?
Answer and explanation
Correct answer: 6.0
The second term of an AP is obtained by adding the common difference to the first term: \(a_2=a+d=3.5+2.5=6.0\). Therefore, 6.0 is correct. Choosing 5.5 results from an incorrect addition of the decimals. Exam tip: use \(a_n=a+(n-1)d\); for the second term, put \(n=2\).
