यदि \(4, 9, 14,\ldots\) और \(20, 16, 12,\ldots\) को पद-दर-पद जोड़ा जाए, तो नया अनुक्रम कैसा होगा?
If \(4, 9, 14,\ldots\) and \(20, 16, 12,\ldots\) are added term by term, what type will the new sequence be?
Explanation opens after your attempt
A. (d=1) वाली अंकगणितीय श्रेणीArithmetic progression with (d=1)
Concept
The common differences are (5) and (-4), so the sum sequence has (d=1). The termwise sum of two arithmetic progressions is also an arithmetic progression.
Why this answer is correct
The correct answer is A. (d=1) वाली अंकगणितीय श्रेणी / Arithmetic progression with (d=1). The common differences are (5) and (-4), so the sum sequence has (d=1). The termwise sum of two arithmetic progressions is also an arithmetic progression.
Exam Tip
दोनों सार्व अंतर (5) और (-4) हैं, इसलिए योग अनुक्रम का (d=1)। दो अंकगणितीय श्रेणियों का पद-दर-पद योग भी अंकगणितीय श्रेणी होता है।
