Find the pair of numbers that does not belong to the group for lack of a common property: 16–18 56–63 96–108 86–99 ✅ *Correct Answer: 86–99* Explanation: *All other number pairs follow the ratio 8:9:* 16:18 = 8:9 56:63 = 8:9 96:108 = 8:9 But 86:99 ≠ 8:9 (since 86 ÷ 99 ≈ 0.868, not 0.888…) Hence, 86–99 is the pair that does not fit the pattern. *🎯 Why This Question Matters for Students* Understanding number relationships and pattern recognition is essential for: 1.
