Answer and explanation
Correct answer: 4
For the eighth term, substitute \(n=8\). Thus, \(a_8=\frac{8}{2}=4\). Therefore, the correct answer is 4. Option 2 would result from using \(n=4\), which represents the fourth term. Exam tip: substitute the required term number carefully in an nth-term formula.
