To solve the problem, we need to identify the pattern in each sequence and then continue the pattern by filling in the missing numbers. Let's analyze each sequence step by step:
---
1. Sequence: 20, 21, 22, 23, __, __, __, __
-
Pattern: The numbers are increasing by 1.
-
Next numbers: 24, 25, 26, 27
-
Completed sequence: 20, 21, 22, 23,
24, 25, 26, 27
---
2. Sequence: 10, 12, 14, 16, __, __, __, __
-
Pattern: The numbers are increasing by 2.
-
Next numbers: 18, 20, 22, 24
-
Completed sequence: 10, 12, 14, 16,
18, 20, 22, 24
---
3. Sequence: 10, 20, 30, 40, __, __, __, __
-
Pattern: The numbers are increasing by 10.
-
Next numbers: 50, 60, 70, 80
-
Completed sequence: 10, 20, 30, 40,
50, 60, 70, 80
---
4. Sequence: 20, 23, 26, 29, __, __, __, __
-
Pattern: The numbers are increasing by 3.
-
Next numbers: 32, 35, 38, 41
-
Completed sequence: 20, 23, 26, 29,
32, 35, 38, 41
---
5. Sequence: 30, 35, 40, 45, __, __, __, __
-
Pattern: The numbers are increasing by 5.
-
Next numbers: 50, 55, 60, 65
-
Completed sequence: 30, 35, 40, 45,
50, 55, 60, 65
---
6. Sequence: 20, 19, 18, 17, __, __, __, __
-
Pattern: The numbers are decreasing by 1.
-
Next numbers: 16, 15, 14, 13
-
Completed sequence: 20, 19, 18, 17,
16, 15, 14, 13
---
7. Sequence: 55, 50, 45, 40, __, __, __, __
-
Pattern: The numbers are decreasing by 5.
-
Next numbers: 35, 30, 25, 20
-
Completed sequence: 55, 50, 45, 40,
35, 30, 25, 20
---
8. Sequence: 16, 20, 24, 28, __, __, __, __
-
Pattern: The numbers are increasing by 4.
-
Next numbers: 32, 36, 40, 44
-
Completed sequence: 16, 20, 24, 28,
32, 36, 40, 44
---
Final Answer:
\[
\boxed{
\begin{array}{l}
20, 21, 22, 23, \mathbf{24, 25, 26, 27} \\
10, 12, 14, 16, \mathbf{18, 20, 22, 24} \\
10, 20, 30, 40, \mathbf{50, 60, 70, 80} \\
20, 23, 26, 29, \mathbf{32, 35, 38, 41} \\
30, 35, 40, 45, \mathbf{50, 55, 60, 65} \\
20, 19, 18, 17, \mathbf{16, 15, 14, 13} \\
55, 50, 45, 40, \mathbf{35, 30, 25, 20} \\
16, 20, 24, 28, \mathbf{32, 36, 40, 44}
\end{array}
}
\]
