Abstract Reasoning Flashcards

A 3×3 grid has shapes that change color left to right: white, gray, black. The middle row has gray, black, ?

Answer: White

The color sequence in each row must contain white, gray, and black once, so the missing color is white.

In a pattern, odd-numbered positions have stars and even-numbered positions have hexagons. What shape is in position 9?

Answer: Star

9 is odd, so position 9 contains a star.

A figure has 4 quadrants. Moving clockwise, a black dot starts in the top-left and moves one quadrant each step. After 6 steps, which quadrant holds the dot?

Answer: Top-right

The dot cycles through 4 positions; 6 mod 4 = 2, placing it 2 steps clockwise from top-left, which is top-right.

Each row in a matrix shows shapes with an increasing number of internal lines: 0, 1, 2 lines. The third row begins with a shape with 2 lines, then 0 lines, then ?

Answer: 1 line

Each row must contain 0, 1, and 2 internal lines exactly once, so the missing value is 1 line.

A shape series alternates between horizontal and vertical orientations: horizontal rectangle, vertical rectangle, horizontal oval, vertical oval, horizontal diamond, ?

Answer: Vertical diamond

Each shape type alternates horizontal then vertical, so after horizontal diamond comes vertical diamond.

In a logical matrix, the product of numbers in each row equals 24. Row 1: 2, 4, 3. Row 2: 6, 2, 2. Row 3: 4, ?, 3

Answer: 2

4 × ? × 3 = 24 → ? = 24 ÷ 12 = 2.

In a sequence of figures, each figure has one fewer side than the previous. The sequence starts at 8 sides. What shape is in position 5?

Answer: Square (4 sides)

Starting at 8 sides and subtracting 1 per step: position 5 = 8 − 4 = 4 sides, which is a square.
