In a sequence of shapes, each shape gains one additional side with each step: triangle → square → pentagon → ? What comes next?

Answer: Hexagon

Each step adds one side: triangle (3) → square (4) → pentagon (5) → hexagon (6).

A pattern shows alternating shaded and unshaded circles arranged in rows. In row 1 there is 1 shaded circle; in row 2 there are 2 unshaded; in row 3 there are 3 shaded. How many unshaded circles are in row 4?

Answer: 4

Row 4 follows the alternating rule (unshaded) and the count equals the row number, giving 4 unshaded circles.

Each box in a set contains arrows pointing in a specific direction rotating 90° clockwise each step: up → right → down → left → ? What comes next?

Answer: Up

After four 90° clockwise rotations the arrow returns to pointing up.

A matrix has 3 rows and 3 columns. Each row contains a circle, square, and triangle. Each column also contains each shape once. The top-left is a circle, top-middle is a square. What shape is in the top-right?

Answer: Triangle

With circle and square already in the top row, the top-right cell must contain a triangle.

In Set A, all figures have an even number of sides. In Set B, all figures have an odd number of sides. A hexagon belongs to which set?

Answer: Set A

A hexagon has 6 sides, which is even, so it belongs to Set A.

Shapes in a series increase in size by a fixed ratio. If the first shape has area 4 cm² and the third has area 36 cm², what is the area of the second shape?

Answer: 12 cm²

The ratio between consecutive terms is √(36/4) = 3, so the second shape has area 4 × 3 = 12 cm².
