Educational pattern recognition worksheet for children.

Problem: Solve the pattern problems and explain the solution.

The image contains several pattern-related tasks. Let's solve each one step by step.

---

#### Task 1: Spot the Pattern
Pattern:
```
O O O O
X X X X
O O O O
X X X X
O O O O
X X X X
O O O O
? ? ? ?
```

- Observation: The pattern alternates between rows of `O` and `X`. Each row consists of four identical symbols.
- Solution: The missing row should follow the alternating pattern. Since the last visible row is `O O O O`, the next row should be `X X X X`.

Answer:
```
X X X X
```

#### Task 2: Write the Next 3 Numbers in This Pattern
Pattern:
```
1, 2, 3, 4, 1, 2, 3, 4, ...
```

- Observation: The sequence repeats every four numbers: `1, 2, 3, 4`.
- Solution: The next three numbers are simply the continuation of the repeating sequence.

Answer:
```
1, 2, 3
```

#### Task 3: Draw the Next Icon to Complete the Pattern
Pattern:
```
Yellow Circle, Red Square, Yellow Circle, Red Square, Yellow Circle, Red Square, ...
```

- Observation: The pattern alternates between a yellow circle and a red square.
- Solution: The next icon should be a red square, as the last visible icon is a yellow circle.

Answer:
```
Red Square
```

#### Task 4: Complete the Last 2 Boxes in This Pattern
Pattern:
```
Blue Triangle, Green Circle, Blue Triangle, Green Circle, Blue Triangle, Green Circle, ?, ?
```

- Observation: The pattern alternates between a blue triangle and a green circle.
- Solution: The next two boxes should continue this alternating pattern.

Answer:
```
Blue Triangle, Green Circle
```

---

#### Task 5: Shade the Last 2 Patterns
Pattern:
```
Yellow Square, Blue Square, Yellow Square, Blue Square, Yellow Square, Blue Square, ?, ?
```

- Observation: The pattern alternates between a yellow square and a blue square.
- Solution: The last two patterns should continue this alternating sequence.

Answer:
```
Yellow Square, Blue Square
```

---

#### Task 6: Write the Last 2 Letters
Pattern:
```
A, Z, X, Y, W, V, U, T, ?, ?
```

- Observation: The pattern involves two interleaved sequences:
- Sequence 1: `A, X, W, U, ...` (decreasing alphabetically by 3 letters each time).
- Sequence 2: `Z, Y, V, T, ...` (decreasing alphabetically by 1 letter each time).
- Solution:
- For Sequence 1: After `U`, the next letter is `R` (decrease by 3 from `U`).
- For Sequence 2: After `T`, the next letter is `S` (decrease by 1 from `T`).

Answer:
```
R, S
```
