What is the common difference in the sequence (2.5,3.0,3.5,4.0,\ldots)?अनुक्रम (2.5,3.0,3.5,4.0,\ldots) में सार्व अंतर क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 0.50.5
The common difference is found by subtracting a term from the term immediately after it. Here, d = 3.0 - 2.5 = 0.5 and 3.5 - 3.0 = 0.5, so the common difference is 0.5. The value 2.5 is the first term, not the difference. Exam tip: In an AP, subtract any term from the next consecutive term.सार्व अंतर दो क्रमागत पदों का अंतर होता है। यहाँ, d = 3.0 - 2.5 = 0.5 और 3.5 - 3.0 = 0.5, इसलिए सार्व अंतर 0.5 है। 2.5 पहला पद है, अंतर नहीं। परीक्षा टिप: किसी भी AP में बाद वाले पद में से ठीक पहले वाला पद घटाएँ।
