यदि \(8,13,18,\ldots\) और \(4,10,16,\ldots\) के पद-दर-पद अंतर से अनुक्रम बने तो उसका (d) क्या होगा?
If a sequence is formed by termwise difference of \(8,13,18,\ldots\) and \(4,10,16,\ldots\), what will be its (d)?
Explanation opens after your attempt
A. (-1)
Concept
The first sequence has (d=5) and the second has (d=6), so the difference sequence has (d=5-6=-1). In termwise difference, take the difference of common differences.
Why this answer is correct
The correct answer is A. (-1). The first sequence has (d=5) and the second has (d=6), so the difference sequence has (d=5-6=-1). In termwise difference, take the difference of common differences.
Exam Tip
पहले अनुक्रम का (d=5) और दूसरे का (d=6) है, इसलिए अंतर अनुक्रम का (d=5-6=-1)। पद-दर-पद अंतर में सार्व अंतरों का अंतर लें।
