To solve this problem, we need to fill in the missing numbers in the grid. The grid counts from 1 to 100, row by row. Each row has 10 numbers.
Let’s go row by row and find the missing numbers:
Row 1 (1–10):
Numbers given: 1, 2, 3, 4, __, 6, 7, 8, 9, 10
→ Missing number is
5
Row 2 (11–20):
Given: 11, 12, 13, 14, 15, 16, 17, __, 19, 20
→ Missing number is
18
Row 3 (21–30):
Given: 21, __, 23, 24, 25, __, 27, 28, 29, 30
→ Missing numbers are
22 and
26
Row 4 (31–40):
Given: 31, 32, 33, __, 35, 36, 37, 38, 39, 40
→ Missing number is
34
Row 5 (41–50):
Given: 41, 42, 43, 44, __, 46, 47, 48, __, 50
→ Missing numbers are
45 and
49
Row 6 (51–60):
Given: 51, __, 53, 54, 55, 56, 57, 58, 59, __
→ Missing numbers are
52 and
60
Row 7 (61–70):
Given: 61, 62, 63, 64, __, 66, __, 68, 69, 70
→ Missing numbers are
65 and
67
Row 8 (71–80):
Given: __, 72, 73, __, 75, 76, 77, 78, __, 80
→ Missing numbers are
71,
74, and
79
Row 9 (81–90):
Given: 81, 82, __, 84, 85, __, 87, __, 89, 90
→ Missing numbers are
83,
86, and
88
Row 10 (91–100):
Given: __, 92, 93, 94, 95, 96, __, 98, 99, __
→ Missing numbers are
91,
97, and
100
Now let’s list all missing numbers in order as they appear in the grid (left to right, top to bottom):
- Row 1: 5
- Row 2: 18
- Row 3: 22, 26
- Row 4: 34
- Row 5: 45, 49
- Row 6: 52, 60
- Row 7: 65, 67
- Row 8: 71, 74, 79
- Row 9: 83, 86, 88
- Row 10: 91, 97, 100
Final Answer:
5, 18, 22, 26, 34, 45, 49, 52, 60, 65, 67, 71, 74, 79, 83, 86, 88, 91, 97, 100
