समानांतर श्रेढ़ी में \(a_1=4\) और \(a_6=24\) है। समान अंतर क्या है?
In an arithmetic progression, \(a_1=4\) and \(a_6=24\). What is the common difference?
Explanation opens after your attempt
D. (4)
Concept
\(a_6=a_1+5d\), so (24=4+5d) and (d=4). Count the number of gaps between the two terms.
Why this answer is correct
The correct answer is D. (4). \(a_6=a_1+5d\), so (24=4+5d) and (d=4). Count the number of gaps between the two terms.
Exam Tip
\(a_6=a_1+5d\), इसलिए (24=4+5d) और (d=4)। दो पदों के बीच अंतरों की संख्या गिनें।
