Which sequence starts with (64) and subtracts (8) each time?कौन सा क्रम (64) से शुरू होकर हर बार (8) घटाता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(64, 56, 48, 40\)\(64, 56, 48, 40\)
In the sequence \(64, 56, 48, 40\), the differences between consecutive terms are \(56-64=-8\), \(48-56=-8\), and \(40-48=-8\). Thus, 8 is subtracted each time. In option D, the terms decrease by 16, so it is not correct. Exam tip: Find the difference between consecutive terms to check a sequence rule quickly.क्रम \(64, 56, 48, 40\) में क्रमागत पदों का अंतर \(56-64=-8\), \(48-56=-8\) और \(40-48=-8\) है। इसलिए प्रत्येक बार 8 घटाया गया है। विकल्प D में प्रत्येक बार 16 घटता है, इसलिए वह सही नहीं है। परीक्षा टिप: क्रमागत दो पदों का अंतर निकालकर नियम तुरंत जाँचें।
