Explanation opens after your attempt
B. (298)
Concept
\(a_6=426\) and \(a_4=124\). The correct difference is (302), so the listed options do not match.
Why this answer is correct
The correct answer is B. (298). \(a_6=426\) and \(a_4=124\). The correct difference is (302), so the listed options do not match.
Exam Tip
\(a_6=426\) और \(a_4=124\) नहीं बल्कि \(a_4=124\) है। इसलिए सही अंतर (302) नहीं है।
