AR: Type 2 — Sequence Completion

How Sequence Questions Work

You are shown a series of shapes (typically 4 frames) that transform following a consistent rule. One frame is missing (or you must identify the next frame). You choose from 4 options.

Common Sequence Transformations

1. Rotation: A shape rotates by a fixed angle each frame (45°, 90°, 180°)
2. Translation: A shape moves in a consistent direction (one position right, down, etc.)
3. Size change: A shape grows or shrinks progressively
4. Shading cycle: A shape cycles through fills (black → grey → white → black)
5. Shape morphing: The number of sides increases (triangle → square → pentagon → hexagon)
6. Addition/subtraction: An element is added or removed each frame
7. Combined transformations: Multiple rules apply simultaneously (rotate AND change colour)

Strategy for Sequence Questions

1. Compare Frame 1 to Frame 2 — what changed?
2. Compare Frame 2 to Frame 3 — does the same change apply?
3. If yes, apply the same change to find the missing frame
4. If no, look for a different pattern (alternating, cyclic, etc.)
5. Check your answer against ALL frames to ensure consistency

Complex Sequences

Harder sequences combine multiple transformations. Track each element independently:

• Element 1 (e.g., the large circle) may rotate 90° clockwise each frame
• Element 2 (e.g., the small triangle) may change shading each frame
• Element 3 (e.g., the line) may move position each frame

Treat each element as a separate mini-sequence and solve independently.
