What mistake is made if (81, 27, 9, 3) is considered an arithmetic progression?क्रम (81, 27, 9, 3) को समांतर श्रेणी मानने में कौन-सी गलती होगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: The ratio is constant, not the differenceअनुपात समान है, अंतर समान नहीं
This sequence has ratio (\frac{1}{3}), but differences (-54, -18, -6) are not equal. In an arithmetic progression, check difference, not ratio.इस क्रम में अनुपात (\frac{1}{3}) है, पर अंतर (-54, -18, -6) बराबर नहीं हैं। समांतर श्रेणी में अनुपात नहीं, अंतर देखें।
