Abstract Reasoning Matrices Flashcards

A matrix shows the number of dots inside each shape: row 1 = 1, 3, 5; row 2 = 2, 4, 6; row 3 = 3, 5, ?. What is the missing number of dots?

Answer: 7

Each row increments by 2 across columns, and row 3 starts at 3: 3, 5, 7.

In an abstract matrix, each row contains three shapes where the total number of sides sums to 12. Row 2: hexagon (6) + triangle (3) + ? = 12. What shape fills the gap?

Answer: Triangle (3 sides)

6 + 3 + ? = 12, so the missing shape needs 3 sides — a triangle.

A matrix uses a color-mixing rule: when two colors appear in the same column in adjacent rows, the third row shows their mix. Column has red in row 1 and blue in row 2. What color appears in row 3?

Answer: Purple

Red and blue mixed together produce purple.

A matrix has symbols where size is determined by column (small=col 1, medium=col 2, large=col 3) and symbols rotate 90° counterclockwise down each row. A small upward arrow (↑) is in row 1, col 1. What appears in row 2, col 3?

Answer: Large left-pointing arrow (←)

Column 3 means large size; one row down means one 90° counterclockwise rotation: ↑ becomes ←.

In a matrix where each cell's value = (row number) × (column number) − 1, what value belongs in row 3, column 3?

Answer: 8

3 × 3 − 1 = 9 − 1 = 8.

A matrix shows overlapping shapes using a union rule: each cell in column 3 is formed by combining the shapes in columns 1 and 2 of the same row. Row 3: col 1 = square, col 2 = triangle. What is in col 3?

Answer: Square-triangle composite

Column 3 always shows the union of column 1 and column 2 shapes from the same row: square + triangle.

A figure sequence nests shapes: Figure 1 = small triangle; Figure 2 = triangle inside a square; Figure 3 = triangle inside a square inside a circle. What does Figure 4 contain?

Answer: Triangle inside square inside circle inside pentagon

Each figure wraps all previous figures inside one new outer shape; the fourth outer shape in the sequence is a pentagon.
