QPSea Abstract Reasoning: Pattern Recognition 2

Question 1

A sequence shows: 2 dots, 4 dots, 8 dots, 16 dots. How many dots come next?

Accepted Answer

32

Answer

Each term doubles the previous, so 16 × 2 = 32.

Question 2

In a pattern grid, each row contains a circle, square, and triangle in different shades: dark, medium, light. If row 1 is dark-circle, medium-square, light-triangle and row 2 is medium-circle, light-square, dark-triangle, what is row 3?

Accepted Answer

light-circle, dark-square, medium-triangle

Answer

Each shape's shade shifts one step lighter per row (cycling dark→medium→light→dark), giving light-circle, dark-square, medium-triangle.

Question 3

A series of figures shows squares that rotate 45° clockwise each step. After four steps starting from a square aligned with its sides horizontal, what orientation does the figure have?

Accepted Answer

Horizontal (same as start)

Answer

Four steps of 45° = 180°, but a square has 90° symmetry, so after 180° it looks identical to the start.

Question 4

Each figure in a set has a number of sides equal to twice its position number: figure 1 has 2 sides (line), figure 2 has 4 sides (square), figure 3 has 6 sides (hexagon). What shape is figure 4?

Accepted Answer

Octagon

Answer

Figure 4 has 4 × 2 = 8 sides, making it an octagon.

Question 5

A 3×3 matrix contains numbers. Row 1: 1, 4, 9. Row 2: 4, 16, 36. Row 3: 9, 36, ?

Accepted Answer

81

Answer

Each cell equals the product of its row-header and column-header squares: 3² × 3² = 81.
