Which sequence is formed by subtracting (4) each time?कौन सा क्रम हर बार (4) घटाकर बनाया गया है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (32, 28, 24, 20)(32, 28, 24, 20)
In the sequence (32, 28, 24, 20), the differences between consecutive terms are 28 − 32 = −4, 24 − 28 = −4, and 20 − 24 = −4. Hence, 4 is subtracted each time. In option B, 6 is subtracted each time, so it is not correct. Exam tip: Find the difference between consecutive terms to check the rule of a sequence.क्रम (32, 28, 24, 20) में क्रमागत पदों का अंतर है: 28 − 32 = −4, 24 − 28 = −4 और 20 − 24 = −4। इसलिए इसमें हर बार 4 घटाया गया है। विकल्प B में हर बार 6 घटता है, इसलिए वह सही नहीं है। परीक्षा टिप: ऐसे प्रश्नों में लगातार दो पदों का अंतर निकालकर नियम जाँचें।
