Puzzle 1:

```
? 6 ?
? ? ?
25 ? ?
```

#### Step-by-Step Solution:
1. The bottom-left number is 25.
2. The top-middle number is 6.
3. Assume the grid follows a simple arithmetic pattern (e.g., addition or subtraction).

Let's try to fill in the grid:
- If we assume the grid increases by a constant value horizontally and vertically:
- Top row: `? + 6 + ?`
- Middle row: `? + ? + ?`
- Bottom row: `25 + ? + ?`

By trial and error or logical deduction:
- If the grid increases by 5 in each direction:
- Top row: `1 + 6 + 11`
- Middle row: `6 + 11 + 16`
- Bottom row: `11 + 16 + 21`

Thus, the completed grid is:
```
1 6 11
6 11 16
11 16 21
```

Answer for Puzzle 1:
```
1 6 11
6 11 16
11 16 21
```

Puzzle 2:

```
? 2 ?
? ? ?
21 ? ?
```

#### Step-by-Step Solution:
1. The bottom-left number is 21.
2. The top-middle number is 2.
3. Assume the grid follows a simple arithmetic pattern.

Let's try to fill in the grid:
- If we assume the grid increases by a constant value horizontally and vertically:
- Top row: `? + 2 + ?`
- Middle row: `? + ? + ?`
- Bottom row: `21 + ? + ?`

By trial and error or logical deduction:
- If the grid increases by 7 in each direction:
- Top row: `14 + 2 + 9`
- Middle row: `21 + 7 + 12`
- Bottom row: `28 + 14 + 15`

Thus, the completed grid is:
```
14 2 9
21 7 12
28 14 15
```

Answer for Puzzle 2:
```
14 2 9
21 7 12
28 14 15
```

Puzzle 3:

```
? 10 ?
? ? ?
29 ? ?
```

#### Step-by-Step Solution:
1. The bottom-middle number is 29.
2. The top-middle number is 10.
3. Assume the grid follows a simple arithmetic pattern.

Let's try to fill in the grid:
- If we assume the grid increases by a constant value horizontally and vertically:
- Top row: `? + 10 + ?`
- Middle row: `? + ? + ?`
- Bottom row: `? + 29 + ?`

By trial and error or logical deduction:
- If the grid increases by 9 in each direction:
- Top row: `1 + 10 + 19`
- Middle row: `10 + 19 + 28`
- Bottom row: `19 + 29 + 39`

Thus, the completed grid is:
```
1 10 19
10 19 28
19 29 39
```

Answer for Puzzle 3:
```
1 10 19
10 19 28
19 29 39
```

Puzzle 4:

```
? 25 ?
? ? ?
44 ? ?
```

#### Step-by-Step Solution:
1. The bottom-left number is 44.
2. The top-middle number is 25.
3. Assume the grid follows a simple arithmetic pattern.

Let's try to fill in the grid:
- If we assume the grid increases by a constant value horizontally and vertically:
- Top row: `? + 25 + ?`
- Middle row: `? + ? + ?`
- Bottom row: `44 + ? + ?`

By trial and error or logical deduction:
- If the grid increases by 9 in each direction:
- Top row: `16 + 25 + 34`
- Middle row: `25 + 34 + 43`
- Bottom row: `34 + 43 + 52`

Thus, the completed grid is:
```
16 25 34
25 34 43
34 43 52
```

Answer for Puzzle 4:
```
16 25 34

? 68 ?
? 89 ?
```

#### Step-by-Step Solution:
1. The middle-middle number is 68.
2. The bottom-middle number is 89.
3. Assume the grid follows a simple arithmetic pattern.

Let's try to fill in the grid:
- If we assume the grid increases by a constant value horizontally and vertically:
- Top row: `? + ? + ?`
- Middle row: `? + 68 + ?`
- Bottom row: `? + 89 + ?`

By trial and error or logical deduction:
- If the grid increases by 21 in each direction:
- Top row: `27 + 48 + 69`
- Middle row: `48 + 68 + 88`
- Bottom row: `69 + 89 + 109`

Thus, the completed grid is:
```
27 48 69
48 68 88
69 89 109
```

Answer for Puzzle 5:
```
