यदि किसी समान्तर श्रेणी में \(a_6+a_{14}=100\) है तो \(a_{10}\) का मान क्या होगा?
If in an AP \(a_6+a_{14}=100\), what is the value of \(a_{10}\)?
Explanation opens after your attempt
A. (50)
Concept
\(a_{10}\) is the middle term between \(a_6\) and \(a_{14}\), so \(a_{10}=\frac{100}{2}=50\). The average of equally spaced terms is the middle term.
Why this answer is correct
The correct answer is A. (50). \(a_{10}\) is the middle term between \(a_6\) and \(a_{14}\), so \(a_{10}=\frac{100}{2}=50\). The average of equally spaced terms is the middle term.
Exam Tip
\(a_6\) और \(a_{14}\) के बीच का पद \(a_{10}\) है इसलिए \(a_{10}=\frac{100}{2}=50\)। समान दूरी वाले पदों का औसत बीच वाला पद होता है।
