समांतर श्रेणी में \(a_2=9\) और \(a_9=44\) है। \(a_5\) का मान क्या होगा?
In an arithmetic progression, \(a_2=9\) and \(a_9=44\). What is the value of \(a_5\)?
Explanation opens after your attempt
C. (24)
Concept
\(a_9-a_2=7d=35\), so (d=5) and (a_5=9+3(5)=24). Find the common difference first.
Why this answer is correct
The correct answer is C. (24). \(a_9-a_2=7d=35\), so (d=5) and (a_5=9+3(5)=24). Find the common difference first.
Exam Tip
\(a_9-a_2=7d=35\), इसलिए (d=5) और (a_5=9+3(5)=24)। पहले समान अंतर निकालें।
