Question 1/3 Hard Mathematics Arithmetic Progressions (AP) Finding the $n$th term of an AP Class 10 Level 66

यदि समान्तर श्रेणी में \(a_5+a_{17}=132\) है तो \(a_{11}\) का मान क्या होगा?

If in an AP \(a_5+a_{17}=132\), what is the value of \(a_{11}\)?

Explanation opens after your attempt
Correct Answer

C. (66)

Step 1

Concept

\(a_{11}\) is the middle term between \(a_5\) and \(a_{17}\). So \(a_{11}=\frac{132}{2}=66\).

Step 2

Why this answer is correct

The correct answer is C. (66). \(a_{11}\) is the middle term between \(a_5\) and \(a_{17}\). So \(a_{11}=\frac{132}{2}=66\).

Step 3

Exam Tip

\(a_5\) और \(a_{17}\) के बीच का पद \(a_{11}\) है। इसलिए \(a_{11}=\frac{132}{2}=66\)।
