यदि किसी समानांतर श्रेढ़ी में (a=6) और \(a_5=30\) है, तो (d) क्या होगा?
If an arithmetic progression has (a=6) and \(a_5=30\), what is (d)?
Explanation opens after your attempt
C. (6)
Concept
From \(a_5=6+4d=30\), (4d=24) and (d=6). Up to the fifth term, four common differences are added.
Why this answer is correct
The correct answer is C. (6). From \(a_5=6+4d=30\), (4d=24) and (d=6). Up to the fifth term, four common differences are added.
Exam Tip
\(a_5=6+4d=30\) से (4d=24) और (d=6)। पाँचवें पद तक चार समान अंतर जुड़ते हैं।
