Question 1

In a pattern sequence, each shape gains one side per step: triangle, square, pentagon, hexagon. What comes next?

Accepted Answer

Heptagon

Answer

Each shape in the sequence adds one side, so after hexagon (6 sides) comes heptagon (7 sides).

Question 2

A series of figures rotates 45° clockwise each step. If the arrow points right at step 1, which direction does it point at step 5?

Accepted Answer

Left

Answer

Four 45° clockwise rotations = 180°, so after 4 steps it points left; step 5 is 225° from start which is down-left — but starting right (0°) + 4×45° = 180° = left at step 5.

Question 3

Which figure does NOT belong: circle with dot inside, square with dot inside, triangle with dot inside, rectangle with no dot?

Accepted Answer

Rectangle with no dot

Answer

All other figures share the common feature of having a dot inside, so the rectangle with no dot is the odd one out.

Question 4

A pattern alternates: large dark circle, small light circle, large dark circle, small light circle. What is the 7th figure?

Accepted Answer

Large dark circle

Answer

The pattern repeats every 2 figures; odd-numbered positions are always large dark circles.

Question 5

Three shapes — ○ △ □ — are placed in a 3×3 grid so each row and column contains each shape once. If row 1 is ○ △ □ and row 2 is △ □ ○, what is row 3?

Accepted Answer

□ ○ △

Answer

Each column must contain all three shapes once; column 1 has ○ and △, so it needs □; column 2 has △ and □, so it needs ○; column 3 has □ and ○, so it needs △.
