If \(a_n=\frac{n+2}{2}\), what is the value of \(a_6\)?
Answer and explanation
Correct answer: 4
For the sixth term, substitute \(n=6\) in the rule: \(a_6=\frac{6+2}{2}=\frac{8}{2}=4\). Therefore, the correct answer is 4. Option 3 can result from an incorrect division after adding 6 and 2. Exam tip: in \(a_n\), first substitute the given subscript for \(n\), then simplify step by step.
