समांतर श्रेणी में \(a_5=14\) और \(a_{11}=50\) है। \(a_8\) क्या होगा?
In an arithmetic progression, \(a_5=14\) and \(a_{11}=50\). What is \(a_8\)?
Explanation opens after your attempt
C. (32)
Concept
The increase over six gaps is (36), so (d=6) and (a_8=14+3(6)=32). \(a_8\) lies between the two given terms.
Why this answer is correct
The correct answer is C. (32). The increase over six gaps is (36), so (d=6) and (a_8=14+3(6)=32). \(a_8\) lies between the two given terms.
Exam Tip
छह अंतरों में वृद्धि (36) है, इसलिए (d=6) और (a_8=14+3(6)=32)। \(a_8\) दोनों दिए पदों के बीच आता है।
