QPSea Abstract Reasoning: Pattern Recognition 2 — Questions and Answers
Question 1: A sequence shows: 2 dots, 4 dots, 8 dots, 16 dots. How many dots come next?
- 24
- 32 (Correct answer)
- 64
- 18
Correct answer: 32
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?
- light-circle, dark-square, medium-triangle (Correct answer)
- dark-circle, light-square, medium-triangle
- medium-circle, dark-square, light-triangle
- light-circle, medium-square, dark-triangle
Correct answer: light-circle, dark-square, medium-triangle
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?
- Rotated 135°
- Horizontal (same as start) (Correct answer)
- Rotated 45°
- Rotated 90°
Correct answer: Horizontal (same as start)
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?
- Octagon (Correct answer)
- Pentagon
- Heptagon
- Nonagon
Correct answer: Octagon
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, ?
- 72
- 81 (Correct answer)
- 64
- 45
Correct answer: 81
Each cell equals the product of its row-header and column-header squares: 3² × 3² = 81.
Question 6: In a sequence of symbols, each new symbol is formed by adding one element to the previous (a circle gains a line, then a dot, then a second line). Which feature does the fifth symbol have?
- Circle with two lines and a dot
- Circle with three dots
- Circle with two lines and two dots (Correct answer)
- Plain circle
Correct answer: Circle with two lines and two dots
Following the additive pattern: symbol 5 = circle + line + dot + second line + second dot.
Question 7: A pattern alternates between two transformations: reflection then rotation by 90°. If the starting figure points right, what direction does it point after four transformations?
- Left
- Up
- Down
- Right (Correct answer)
Correct answer: Right
Two full cycles (reflection + 90° rotation × 2) return the figure to its original orientation.
A sequence shows: 2 dots, 4 dots, 8 dots, 16 dots.
