Let's solve the
"Numbers 1–100" puzzle by filling in the missing numbers in the grid.
This is a standard
10×10 number chart where numbers from 1 to 100 are arranged sequentially, row by row. Each row has 10 numbers, increasing by 1 as we move right, and each new row starts with a number 10 greater than the last number of the previous row.
We'll go through each row and fill in the missing numbers based on the sequence.

Step-by-step solution:
#### Row 1: 1 to 10
- Given: 1, 2, __, 4, __, 6, __, __, 9, 10
- Missing: 3 (between 2 and 4), 5 (between 4 and 6), 7 (after 6), 8 (before 9)
- So:
3, 5, 7, 8
#### Row 2: 11 to 20
- Given: 11, __, 13, __, 15, __, 17, __, 19, __
- Missing: 12, 14, 16, 18, 20
- So:
12, 14, 16, 18, 20
#### Row 3: 21 to 30
- Given: __, 22, __, 24, __, 26, __, 28, __, 30
- Missing: 21, 23, 25, 27, 29
- So:
21, 23, 25, 27, 29
#### Row 4: 31 to 40
- Given: 31, __, 33, __, 35, __, __, 38, 39, __
- Missing: 32, 34, 36, 37, 40
- So:
32, 34, 36, 37, 40
#### Row 5: 41 to 50
- Given: __, 42, __, 44, __, 46, 47, __, 49, 50
- Missing: 41, 43, 45, 48
- So:
41, 43, 45, 48
#### Row 6: 51 to 60
- Given: 51, __, __, 54, 55, __, 57, __, 59, __
- Missing: 52, 53, 56, 58, 60
- So:
52, 53, 56, 58, 60
#### Row 7: 61 to 70
- Given: __, 62, 63, __, __, 66, __, 68, __, 70
- Missing: 61, 64, 65, 67, 69
- So:
61, 64, 65, 67, 69
#### Row 8: 71 to 80
- Given: 71, __, 73, __, __, 76, 77, __, 79, 80
- Missing: 72, 74, 75, 78
- So:
72, 74, 75, 78
#### Row 9: 81 to 90
- Given: 81, 82, __, 84, 85, __, __, 88, __, __
- Missing: 83, 86, 87, 89, 90
- So:
83, 86, 87, 89, 90
#### Row 10: 91 to 100
- Given: 91, __, 93, 94, __, 96, 97, 98, __, 100
- Missing: 92, 95, 99
- So:
92, 95, 99

Explanation:
- The pattern is sequential counting from 1 to 100.
- Each row increases by 1 left to right.
- Each column increases by 10 top to bottom.
- Use known numbers to infer missing ones by checking adjacent cells.
This exercise helps reinforce number recognition, counting, and understanding place value (tens and ones).
✔ All missing numbers have been correctly filled in!
