यदि \(a_n=5n-2\) है, तो इस समांतर श्रेणी का सार्व अंतर क्या है?
If \(a_n=5n-2\), what is the common difference of this arithmetic progression?
Explanation opens after your attempt
C. (5)
Concept
In the linear rule \(a_n=5n-2\), the coefficient of (n) is the difference (5). In exams, take (k) as (d) in (kn+c).
Why this answer is correct
The correct answer is C. (5). In the linear rule \(a_n=5n-2\), the coefficient of (n) is the difference (5). In exams, take (k) as (d) in (kn+c).
Exam Tip
रैखिक नियम \(a_n=5n-2\) में (n) का गुणांक (5) ही अंतर है। परीक्षा में (kn+c) में (k) को (d) मानें।
