यदि \(a_6=28\) और \(a_{15}=82\) है, तो (d) क्या होगा?
If \(a_6=28\) and \(a_{15}=82\), what is (d)?
Explanation opens after your attempt
B. (6)
Concept
\(a_{15}-a_6=9d=54\), so (d=6). There are (9) gaps between the two terms.
Why this answer is correct
The correct answer is B. (6). \(a_{15}-a_6=9d=54\), so (d=6). There are (9) gaps between the two terms.
Exam Tip
\(a_{15}-a_6=9d=54\), इसलिए (d=6)। दो पदों के बीच (9) अंतर हैं।
