Question 1

Complex Pattern: Mandala Missing elements: Missing 2 petals (NE and SW) and center dot How should the pattern be completed?
In mandala, the pattern logic applies consistently. The Missing 2 petals (NE and SW) and center dot must be filled with two petals and center to maintain integrity.
multiple, complex, grid

Question 2

Geometric Pattern: Hexagonal tessellation Current state: 5 hexagons in ring, center empty What element is needed for completion?
In hexagonal tessellation, all positions must follow the same geometric rule. The missing element is the center hexagon to maintain consistency.
geometric, spatial, tessellation

Question 3

Complex Pattern: Grid 4×4 Missing elements: Missing 4 corner cells How should the pattern be completed?
In grid 4×4, the pattern logic applies consistently. The Missing 4 corner cells must be filled with corner cells to maintain integrity.
multiple, complex, grid

Question 4

Pattern: Butterfly wing Current state: right wing: 3 dots, left wing: 2 dots What is needed to complete the symmetrical pattern?
For perfect symmetry in a butterfly wing, both sides must match. Currently right wing: 3 dots, left wing: 2 dots, so we need to add one dot.
symmetry, mirror, completion

Question 5

Pattern: Star Current state: upper: 5 rays, lower: 3 rays What is needed to complete the symmetrical pattern?
For perfect symmetry in a star, both sides must match. Currently upper: 5 rays, lower: 3 rays, so we need to add two rays.
symmetry, mirror, completion

Question 6

Complex Pattern: Mosaic Missing elements: Missing 4 tiles forming a square How should the pattern be completed?
In mosaic, the pattern logic applies consistently. The Missing 4 tiles forming a square must be filled with 2×2 block to maintain integrity.
multiple, complex, grid

Question 7

Logical Pattern: Count progression Rule: ● → ●● → ●●● → ? What logically completes the pattern?
Following the logical rule: ● → ●● → ●●● → ?. Therefore, the next element is four dots.
logical, rules, sequence

Question 8

Pattern: Star Current state: upper: 5 rays, lower: 3 rays What is needed to complete the symmetrical pattern?
For perfect symmetry in a star, both sides must match. Currently upper: 5 rays, lower: 3 rays, so we need to add two rays.
symmetry, mirror, completion

Question 9

Pattern: ● Circle (4 equal parts) ┌─────┬─────┐ │ ● │ ● │ ├─────┼─────┤ │ ● │ ? │ └─────┴─────┘ Missing: bottom-right quarter What symbol completes the pattern?
In a symmetrical ● circle (4 equal parts), all four quarters must be identical. The missing bottom-right quarter should be a solid circle like the others.
missing, quarter, basic, symmetry

Question 10

Size progression pattern: ⚪ (tiny) → ○ (medium) → ● (large) → ? What size comes next?
Size increases progressively: tiny → small → medium → large. The missing size is small (◯).
size, progression, sequence

Question 11

Pattern: ■ Square grid ┌─────┬─────┐ │ ? │ ■ │ ├─────┼─────┤ │ ■ │ ■ │ └─────┴─────┘ Missing: top-left quarter What symbol completes the pattern?
In a symmetrical ■ square grid, all four quarters must be identical. The missing top-left quarter should be a solid square like the others.
missing, quarter, basic, symmetry

Question 12

Find the odd one and complete: ○ ○ ■ ? What should replace '?' to make a consistent pattern?
■ is the odd one out because it's different from ○. To make all elements consistent, replace '?' with ○.
odd-one-out, consistency, pattern

Question 13

Geometric Pattern: Hexagonal tessellation Current state: 5 hexagons in ring, center empty What element is needed for completion?
In hexagonal tessellation, all positions must follow the same geometric rule. The missing element is the center hexagon to maintain consistency.
geometric, spatial, tessellation

Question 14

Pattern: Pinwheel with 120° rotational symmetry Current: blades at: NE, NW, SW Missing: SE position What completes the pattern?
For 120° rotational symmetry, all positions must be filled identically. The SE position needs the same element as the others → SE blade.
rotation, symmetry, spatial

Question 15

Pattern: Diamond with 120° rotational symmetry Current: corners filled: top, left, right Missing: bottom position What completes the pattern?
For 120° rotational symmetry, all positions must be filled identically. The bottom position needs the same element as the others → bottom corner.
rotation, symmetry, spatial

Question 16

Geometric Pattern: Triangular grid Current state: Top 6 triangles complete, bottom 2 missing What element is needed for completion?
In triangular grid, all positions must follow the same geometric rule. The missing element is the two bottom triangles to maintain consistency.
geometric, spatial, tessellation

Question 17

Pattern: ◆ Diamond pattern Missing: left quarter in ◆ Diamond pattern Missing: left quarter What symbol completes the pattern?
In a symmetrical ◆ diamond pattern, all four quarters must be identical. The missing left quarter should be a solid diamond like the others.
missing, quarter, basic, symmetry

Question 18

Pattern: Flower Current state: top: 5 petals, bottom: 4 petals What is needed to complete the symmetrical pattern?
For perfect symmetry in a flower, both sides must match. Currently top: 5 petals, bottom: 4 petals, so we need to add one petal.
symmetry, mirror, completion

Question 19

Logical Pattern: Boolean Rule: True → False → True → False → ? What logically completes the pattern?
Following the logical rule: True → False → True → False → ?. Therefore, the next element is true.
logical, rules, sequence

Question 20

3D/Perspective Pattern: Pyramid Missing: Missing back corner of base What completes the perspective drawing?
In perspective drawing, all parallel lines converge to vanishing points. The Missing back corner of base must follow these same convergence rules → base corner.
