Question 1

In a 3×3 matrix, the number of dots increases by 2 across each row and by 3 down each column. The top-left cell has 1 dot. How many dots are in the bottom-right cell?

Accepted Answer

11

Answer

Moving right 2 columns adds 4 dots; moving down 2 rows adds 6 dots; 1 + 4 + 6 = 11.

Question 2

A figure is reflected horizontally, then rotated 90° clockwise. Which single transformation is equivalent?

Accepted Answer

90° counter-clockwise rotation

Answer

Combining a horizontal reflection with a 90° clockwise rotation is equivalent to a single 90° counter-clockwise rotation.

Question 3

When a question asks you to find the 'odd one out,' which approach is most reliable?

Accepted Answer

List attributes of all shapes and find which one violates a shared rule

Answer

Systematically listing attributes (sides, shading, size, orientation) reveals which shape breaks the pattern the others share.

Question 4

Symbols inside a shape decrease by one per row from top to bottom: 5, 4, 3. The border of the shape changes from dashed to solid to dashed. What are the contents and border in the missing bottom-right cell (Row 3)?

Accepted Answer

3 symbols, dashed border

Answer

Row 3 has 3 symbols and follows the dashed-solid-dashed pattern, so the border is dashed.

Question 5

A series shows: pentagon, hexagon, heptagon, octagon. What comes next?

Accepted Answer

Nonagon

Answer

Each shape adds one side: 5, 6, 7, 8 → next is 9 sides = nonagon.
