समांतर श्रेणी में \(a_4=10\) और \(a_{10}=34\) है। \(a_7\) क्या होगा?
In an arithmetic progression, \(a_4=10\) and \(a_{10}=34\). What is \(a_7\)?
Explanation opens after your attempt
C. (22)
Concept
The increase over six gaps is (24), so (d=4) and (a_7=10+3(4)=22). \(a_7\) lies between the two given terms.
Why this answer is correct
The correct answer is C. (22). The increase over six gaps is (24), so (d=4) and (a_7=10+3(4)=22). \(a_7\) lies between the two given terms.
Exam Tip
छह अंतरों में वृद्धि (24) है, इसलिए (d=4) और (a_7=10+3(4)=22)। \(a_7\) दोनों दिए पदों के बीच आता है।
