### Mathematical Patterns and Sequences

This section will help you understand how to identify and work with patterns in sequences of numbers. The exercises provided will involve circle formations and stacked cubes to help demonstrate these concepts.

#### Circle Formation Questions
1. **What is the total number of circles in picture 5? Explain your answer.**
2. **How many circles are needed to form triangle picture 7? Give a reason for your answer.**
3. **How many circles are needed to form triangle picture 8? Give a reason for your answer.**
4. **Complete the table below. Show all your calculations:**

| Picture number     | 1 | 2 | 3 | 4 | 5  | 6  | 12 | 15 |
|--------------------|---|---|---|---|----|----|----|----|
| Number of circles  | 1 | 3 | 6 | 10 | 15 | 16 | 20 | 23 |

*(16 marks)*

#### Cube Stacking Questions
Study the diagrams and answer the following questions:

- **Diagram Explanation:**
    - **Stack 1** shows a single cube.
    - **Stack 2** shows a stack of 8 cubes arranged in a 2x2x2 format.
    - **Stack 3** shows a stack of 27 cubes arranged in a 3x3x3 format.

**Questions:**
1. **How many cubes will there be in stack 5?**
2. **Complete the table:**

| Stack number      | 1 | 2 | 3 | 4 | 5  | 6  | 10 |
|-------------------|---|---|---|---|----|----|----|
| Number of cubes   | 1 | 8 | 27|   | 125| 216|    |

3. **Write down the rule to calculate the number of cubes for any stack number:**

*(7 marks)*
