Question 1

In a 3×3 matrix, the number of dots in each row increases by 1. The first row has 1, 2, 3 dots; the second row has 2, 3, 4 dots. What should the third row contain?

Accepted Answer

3, 4, 5 dots

Answer

Each row starts with one more dot than the previous row. Row 1: 1,2,3. Row 2: 2,3,4. Row 3: 3,4,5.

Question 2

A sequence of symbols rotates 45° clockwise each step. If the first symbol is a vertical up arrow (↑), what does the fifth symbol look like?

Accepted Answer

↓ (downward)

Answer

Each step adds 45° clockwise: ↑(step1) → ↗(step2) → →(step3) → ↘(step4) → ↓(step5). After 4 rotations of 45°, the total is 180°, so the arrow now points downward.

Question 3

In an abstract pattern, shapes alternate between filled (black) and outline (white) in a checkerboard fashion across a 3×3 grid. The top-left is filled. What is the centre cell?

Accepted Answer

Filled (black)

Answer

In a checkerboard pattern, same-coloured cells are on the same diagonal. The centre is at position (2,2). Since (1,1) is filled, and the sum 2+2=4 is even (same parity as 1+1=2), the centre is also filled.

Question 4

Each figure in a series gains one side: triangle, square, pentagon... What is the 7th figure in the series?

Accepted Answer

Octagon

Answer

Triangle=3 sides (figure 1), square=4 (figure 2), pentagon=5 (figure 3). Pattern: figure n has n+2 sides. Figure 7 has 7+2=9 sides — a nonagon.

Question 5

In a number matrix, each row sums to the same total. Row 1: 3, 7, 2 (sum=12). Row 2: 5, ?, 4 (sum must be 12). What is the missing number?

Accepted Answer

3

Answer

Row 2 must sum to 12: 5 + ? + 4 = 12. So ? = 12 - 5 - 4 = 3.
