यदि समानांतर श्रेढ़ी में \(a_6=41\) और (d=7) है, तो \(a_3\) क्या होगा?
If an arithmetic progression has \(a_6=41\) and (d=7), what is \(a_3\)?
Explanation opens after your attempt
B. (20)
Concept
From \(a_6\) to \(a_3\), move back (3) gaps, so (a_3=41-3(7)=20). When moving backward subtract the common difference.
Why this answer is correct
The correct answer is B. (20). From \(a_6\) to \(a_3\), move back (3) gaps, so (a_3=41-3(7)=20). When moving backward subtract the common difference.
Exam Tip
\(a_6\) से \(a_3\) तक (3) अंतर पीछे जाना है, इसलिए (a_3=41-3(7)=20)। पीछे जाते समय समान अंतर घटाएं।
