Explanation opens after your attempt
C. (324)
Concept
The first sum gives (2a+22d=156) and the second gives (2a+30d=252). (d=12) and \(a_{34}=324\).
Why this answer is correct
The correct answer is C. (324). The first sum gives (2a+22d=156) and the second gives (2a+30d=252). (d=12) and \(a_{34}=324\).
Exam Tip
पहले योग से (2a+22d=156) और दूसरे से (2a+30d=252)। (d=12) और \(a_{34}=324\)।
