Answer 1

To determine which pattern will have a diamond as the eighth shape, let's analyze the repeating rules provided:

1. **diamond, square, triangle**: This pattern repeats every 3 shapes. The sequence is:
- 1st: diamond
- 2nd: square
- 3rd: triangle
- 4th: diamond
- 5th: square
- 6th: triangle
- 7th: diamond
- 8th: square (Not a diamond)

2. **circle, triangle, diamond**: This pattern also repeats every 3 shapes. The sequence is:
- 1st: circle
- 2nd: triangle
- 3rd: diamond
- 4th: circle
- 5th: triangle
- 6th: diamond
- 7th: circle
- 8th: triangle (Not a diamond)

3. **triangle, diamond**: This pattern repeats every 2 shapes. The sequence is:
- 1st: triangle
- 2nd: diamond
- 3rd: triangle
- 4th: diamond
- 5th: triangle
- 6th: diamond
- 7th: triangle
- 8th: diamond (This is a diamond)

4. **diamond, circle**: This pattern repeats every 2 shapes. The sequence is:
- 1st: diamond
- 2nd: circle
- 3rd: diamond
- 4th: circle
- 5th: diamond
- 6th: circle
- 7th: diamond
- 8th: circle (Not a diamond)

Based on the analysis, the only rule that has a diamond as the eighth shape is:

**triangle, diamond**.
