Explanation Given numbers: 8, 13, 25, 43, 11 Step 1: Add the numbers 8 + 13 + 25 + 43 + 11 = 100 Step 2: Divide by the number of values 100 ÷ 5 = 20
Answer: 40, 100
Explanation First and Third Numbers: 9² = 81 8² = 64 So for 10: 10² = 100 → third number is 100 Now the middle number: 9 × 5 = 45 8 × 4.5 = 36 Seems like: Middle number = First number × 5 (for 9), and × 4.5 (for 8) Let’s check the pattern: 9 → ×5 = 45 8 → ×4.5 = 36 So 10 → ×4 = 40 Final Set: 10 (40) (100)
