Raven's Abstract Reasoning Flashcards

A 3x3 matrix shows shapes where each row contains a large, medium, and small version of the same shape. Each column contains a circle, square, and triangle (one each). The top-right cell has a large circle and the middle-right cell has a medium triangle. What is in the bottom-right cell?

Answer: Small square

The right column needs a small size (large and medium are taken) and a square (circle and triangle are taken), giving a small square.

Each figure in a sequence has an outer ring of shapes and an inner shape. The outer ring has 3 shapes in figure 1, 5 in figure 2, and 7 in figure 3. How many shapes are in the outer ring of figure 5?

Answer: 11

The outer ring increases by 2 each step: 3, 5, 7, 9, 11 — figure 5 has 11.

In a Raven's matrix, the rule is that each cell's shape is the geometric union of the shapes in the same row to its left. If row 3 starts with a circle and the second cell adds a square overlapping it, what does the third cell show?

Answer: A circle and a square overlapping

The union rule accumulates all prior shapes, so cell 3 contains both the circle from cell 1 and the square added in cell 2.

A pattern matrix uses the XOR rule: a feature appears in the answer cell only if it appears in exactly one of two reference cells. Cell A has a circle and a star; Cell B has a circle and a triangle. What appears in the answer cell?

Answer: Star and triangle

XOR keeps features unique to one cell: star (only in A) and triangle (only in B); circle appears in both so it is excluded.

In a series of figures, each step removes one line from the previous figure. Figure 1 is a rectangle (4 lines). Figure 3 is a right angle (2 lines). What does Figure 5 look like?

Answer: A point (no lines)

Removing one line per step: fig 1=4, 2=3, 3=2, 4=1, 5=0 — figure 5 has no lines (just a point or blank).

A matrix rule states the number in each cell equals the sum of the cell directly above it and the cell directly to its left. The top-left cell is 1, the top-middle is 2, the middle-left is 3. What is the value of the middle-center cell?

Answer: 5

Middle-center = cell above (top-middle = 2) + cell to its left (middle-left = 3) = 5.

A sequence of figures shows nested squares: figure 1 has 1 square, figure 2 has 2 nested squares, and so on. Each new outer square's side length is 2 cm more than the previous. If the innermost square has a side of 2 cm, what is the side length of the outermost square in figure 4?

Answer: 8 cm

Starting at 2 cm and adding 2 cm per nesting level: figure 4 has 4 squares, outermost = 2 + (3 × 2) = 8 cm.
