Which value fills the blank in (110,\Box,94,86,78)?क्रम (110,\Box,94,86,78) में खाली स्थान कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 102102
This is a decreasing sequence in which each term is 8 less than the previous term: \(110-8=102\) and \(102-8=94\). Therefore, the blank is 102. If 101 were used, the decrease from 110 would be 9, so the common difference would not remain the same. Exam tip: In a missing-term sequence, check the differences using terms on both sides of the blank.यह एक घटता हुआ क्रम है, जिसमें प्रत्येक अगला पद पिछले पद से 8 कम है: \(110-8=102\), \(102-8=94\)। इसलिए खाली स्थान में 102 आएगा। 101 लेने पर 110 से कमी 9 होगी, इसलिए क्रम का समान अंतर नहीं बनेगा। परीक्षा टिप: रिक्त पद वाले क्रम में दोनों ओर के पदों के बीच अंतर जाँचें।
