What is the next term of (90,80,70,60,\ldots)?क्रम (90,80,70,60,\ldots) का अगला पद क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 5050
Each term is 10 less than the preceding term: 90, 80, 70, 60. Therefore, 60 - 10 = 50, so the correct answer is 50. Choosing 45 would give a difference of 15, which does not match the common difference in the sequence. Exam tip: Find the difference between consecutive terms to identify the next term quickly.क्रम में प्रत्येक अगला पद पिछले पद से 10 कम है: 90, 80, 70, 60। इसलिए 60 - 10 = 50, अतः सही उत्तर 50 है। 45 लेने पर अंतर 15 हो जाएगा, जो दिए गए क्रम के समान अंतर से मेल नहीं खाता। परीक्षा टिप: लगातार पदों का अंतर देखकर ऐसे क्रम का अगला पद शीघ्र ज्ञात करें।
