A progression is a sequence where visual elements change gradually and logically from one frame to the next—usually across a row or column. These changes can happen in shape, size, number, direction, or position.

Objective: Identify the pattern of change and apply it to find the missing element.

Common Types:

• Shape Progression
• Size Progression
• Number Progression
• Position Progression
• Line or Bar Count

How to Solve: Examine rows/columns, identify changes, and apply the rule. Use elimination.

Example: Triangle → Square → Circle implies a shape with more sides each step. Apply this to solve.

Shapes may rotate in fixed steps across rows or columns. You must determine the degree and direction.

Goal: Detect how and by how much an element turns.

Types: Fixed-step, alternating, or multi-feature rotations.

How to Solve: Track the rotation, determine the angle/direction, and apply it.

Example: → → ↓ (rotate 90°), ↓ → ? → ↑

Reflections (or flipping) create mirror images—horizontally, vertically, or diagonally.

Goal: Identify the direction of the flip and apply it.

Common: Horizontal, vertical, diagonal reflections.

Example: → → ← (horizontal flip pattern)

This type involves visual math—adding, removing, or merging shapes across rows/columns.

Goal: Identify if shapes or parts are combined or subtracted.

Common: Simple addition, subtraction, overlays, progressive building.

Example: ◯ + ▲ → ◯ with ▲ inside

Color and shading changes—such as grayscale shifts or fill patterns—are common in this type.

Goal: Observe and follow shading or color logic.

Types: Grayscale progression, alternating fills, rotating shades, combined shading.

Example: 25% → 50% → 75% shaded circles.

🔍 Common Visual Logic Operations

• AND (Overlap): Only the parts that exist in both shapes remain.
  Example: Shape A has diagonal lines, Shape B has vertical lines → Result shows overlap only.
• OR (Union): All parts from both shapes appear in the result.
• XOR (Exclusive Or): Only parts in one shape but not both remain—shared areas disappear.
• NOT (Negation): Inverts elements, like turning white to black. Rare in basic versions.

🛠️ How to Solve Logic-Based Questions:

• Look for triads: A + B = C? or C − A = B?
• Compare shapes: What parts are shared or unique?
• Identify operation type: AND, OR, XOR?
• Apply that logic to find the missing element.

✅ Example Problem:
Row 1: A square with a dot, a triangle with the same dot → Result: shape with no dot (XOR).
Row 2: A shape with a vertical line, second shape has the same line → Result: line disappears (XOR again).

💡 Tips: Think like a computer—sketch if needed. Watch out for element positions!
