If (2, 9, 16, 23,\ldots) is written in reverse order, what will happen to the sign of the common difference?यदि (2, 9, 16, 23,\ldots) को उलटे क्रम में लिखा जाए, तो सार्व अंतर का चिह्न कैसा होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It will become negativeवह ऋणात्मक हो जाएगा
The original (d=7), and in reverse order (23,16,9,2,\ldots), (d=-7). Reversing the order changes the sign of the common difference.मूल (d=7) है और उलटा क्रम (23,16,9,2,\ldots) में (d=-7) होगा। क्रम उलटने पर सार्व अंतर का चिह्न बदल जाता है।
