कौन सी जानकारी किसी पूरे अनुक्रम के समांतर श्रेणी होने की गारंटी नहीं देती?
Which information does not guarantee that an entire sequence is an AP?
Explanation opens after your attempt
C. केवल \(a_2-a_1=a_3-a_2\)Only \(a_2-a_1=a_3-a_2\)
Concept
Checking only the first three terms is not enough for the whole sequence. In exams, the full condition must involve every (n) or all consecutive terms.
Why this answer is correct
The correct answer is C. केवल \(a_2-a_1=a_3-a_2\) / Only \(a_2-a_1=a_3-a_2\). Checking only the first three terms is not enough for the whole sequence. In exams, the full condition must involve every (n) or all consecutive terms.
Exam Tip
केवल पहले तीन पदों की जांच पूरे अनुक्रम के लिए पर्याप्त नहीं है। परीक्षा में पूरी शर्त में हर (n) या सभी लगातार पद शामिल होने चाहिए।
