Abstract Pattern Recognition Flashcards

A sequence shows shapes increasing in sides: triangle, square, pentagon, hexagon. What comes next?

Answer: Heptagon

Each shape gains one side, so after hexagon (6 sides) comes heptagon (7 sides).

In a matrix, the top row has 1 dot, 2 dots, 3 dots. The middle row has 2 dots, 4 dots, 6 dots. What is the pattern for the bottom row's third cell if it starts with 3, 6, ?

Answer: 9

Each row multiplies the column number by the row number (3×3=9), following the doubling-per-row pattern.

Shapes alternate between filled and outlined, and between circle and square. The sequence starts: filled circle, outlined square, filled circle, outlined square. What is the 5th shape?

Answer: Filled circle

The pattern repeats every 2 steps, so the 5th element mirrors the 1st: filled circle.

Each figure in a series rotates 45° clockwise. If the arrow starts pointing right (0°), what direction does the 5th figure point?

Answer: Down-left (225°)

After 4 rotations of 45° each (4×45°=180°), the arrow points left, so the 5th starts from left and rotates to 225° (down-left).

A grid pattern uses black, white, and grey cells. In each row, no color repeats in the same column. The first row is Black, White, Grey. The second row is White, Grey, Black. What is the third row?

Answer: Grey, Black, White

This is a Latin square pattern where each color appears exactly once per row and column.

Figures in a series have an increasing number of internal lines: 0, 1, 2, 3. Each figure is also one size larger. What two properties change together?

Answer: Internal complexity and size

Both the number of internal lines and the overall figure size increase by one unit per step.

A pattern has symbols: ★ ● ▲ ★ ● ▲ ★ ● ▲. Which symbol comes at position 11?

Answer: ★

The 3-symbol cycle repeats, and position 11 mod 3 = 2, but since 11=3×3+2, the 2nd symbol in the cycle is ●... wait: pos 1=★, 2=●, 3=▲, 4=★, 10=●, 11=▲... pos 11: 11 mod 3 = 2, so it maps to position 2 = ●. Actually re-checking: pos 1→★(1), 2→●(2), 3→▲(3), 4→★(1), 11 mod 3 = 2 → ●. The pattern at position 11 is ●.
