यदि \(30, 24, 18,\ldots\) से \(2, 7, 12,\ldots\) को पद-दर-पद घटाया जाए, तो नए अनुक्रम का सार्व अंतर क्या होगा?
Explanation opens after your attempt
Correct Answer
A. (-11)
Concept
The first sequence has (d=-6) and the second has (d=5), so the difference sequence has (d=-6-5=-11). In termwise subtraction, the common differences also subtract.
Why this answer is correct
The correct answer is A. (-11). The first sequence has (d=-6) and the second has (d=5), so the difference sequence has (d=-6-5=-11). In termwise subtraction, the common differences also subtract.
Exam Tip
पहले अनुक्रम का (d=-6) और दूसरे का (d=5) है, इसलिए अंतर अनुक्रम का (d=-6-5=-11)। पद-दर-पद घटाव में (d) भी घटते हैं।
