समांतर श्रेणी में \(a_6=41\) और (d=8) है। \(a_1\) क्या होगा?
In an arithmetic progression, \(a_6=41\) and (d=8). What is \(a_1\)?
Explanation opens after your attempt
A. (1)
Concept
\(a_6=a_1+5d\), so \(41=a_1+40\) and \(a_1=1\). To move backward from a given term, subtract common differences.
Why this answer is correct
The correct answer is A. (1). \(a_6=a_1+5d\), so \(41=a_1+40\) and \(a_1=1\). To move backward from a given term, subtract common differences.
Exam Tip
\(a_6=a_1+5d\), इसलिए \(41=a_1+40\) और \(a_1=1\)। दिए पद से पीछे जाने के लिए समान अंतर घटाएं।
