If \(a_8+a_{26}=246\), what is the value of \(a_{17}\)?

Explanation opens after your attempt
Correct Answer

C. (123)

Step 1

The correct answer is C. (123). \(a_{17}\) is equally spaced between \(a_8\) and \(a_{26}\). Therefore \(a_{17}=\frac{246}{2}=123\).

Step 3

Exam Tip

\(a_{17}\), \(a_8\) और \(a_{26}\) के बीच समान दूरी पर है। इसलिए \(a_{17}=\frac{246}{2}=123\)।
