यदि \(a_1=7\) और \(a_{12}=73\) है, तो समान अंतर क्या है?
If \(a_1=7\) and \(a_{12}=73\), what is the common difference?
Explanation opens after your attempt
B. (6)
Concept
\(a_{12}=a_1+11d\), so (73=7+11d) and (d=6). Up to the twelfth term, there are (11) gaps.
Why this answer is correct
The correct answer is B. (6). \(a_{12}=a_1+11d\), so (73=7+11d) and (d=6). Up to the twelfth term, there are (11) gaps.
Exam Tip
\(a_{12}=a_1+11d\), इसलिए (73=7+11d) और (d=6)। बारहवें पद तक (11) अंतर होते हैं।
