यदि समांतर श्रेणी में \(a_5=24\) और \(a_{10}=59\) है, तो \(a_{13}\) क्या होगा?
If an arithmetic progression has \(a_5=24\) and \(a_{10}=59\), what is \(a_{13}\)?
Explanation opens after your attempt
C. (80)
Concept
The increase over five gaps is (35), so (d=7) and (a_{13}=59+3(7)=80). First find (d), then move forward.
Why this answer is correct
The correct answer is C. (80). The increase over five gaps is (35), so (d=7) and (a_{13}=59+3(7)=80). First find (d), then move forward.
Exam Tip
पाँच अंतरों में वृद्धि (35) है, इसलिए (d=7) और (a_{13}=59+3(7)=80)। पहले (d) निकालें फिर आगे बढ़ें।
