यदि \(a_1=9\) और \(a_{15}=93\) है, तो समान अंतर क्या है?
If \(a_1=9\) and \(a_{15}=93\), what is the common difference?
Explanation opens after your attempt
B. (6)
Concept
\(a_{15}=a_1+14d\), so (93=9+14d) and (d=6). Up to the fifteenth term, there are (14) gaps.
Why this answer is correct
The correct answer is B. (6). \(a_{15}=a_1+14d\), so (93=9+14d) and (d=6). Up to the fifteenth term, there are (14) gaps.
Exam Tip
\(a_{15}=a_1+14d\), इसलिए (93=9+14d) और (d=6)। पंद्रहवें पद तक (14) अंतर होते हैं।
