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)
