Which sequence is an arithmetic progression with common difference \(d=-5\)?कौन-सी अनुक्रम एक अंकगणितीय प्रगति (Arithmetic Progression) है जिसका समान अंतर \(d=-5\) है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 10, 5, 0, -510, 5, 0, -5
For an AP with \(d=-5\), each next term must be \(5\) less than the previous term. In \(10, 5, 0, -5\): \(5-10=-5\), \(0-5=-5\), and \((-5)-0=-5\). So the common difference is \(-5\).\(d=-5\) वाली AP में प्रत्येक अगला पद पिछले पद से \(5\) कम होना चाहिए। \(10, 5, 0, -5\) में: \(5-10=-5\), \(0-5=-5\), और \((-5)-0=-5\)। इसलिए समान अंतर \(-5\) है।
