Basic Ability Test Basic Ability Abstract Pattern Recognition 4 — Questions and Answers
Question 1: In a 3×3 grid, the sum of each row equals 15. The first row is 2, 7, 6 and the second row is 9, 5, 1. What must the third row sum to?
- 12
- 13
- 15 (Correct answer)
- 18
Correct answer: 15
The rule states every row sums to 15, so the third row must also sum to 15.
Question 2: Shapes in a pattern increase in size by 50% each step. If step 1 has a shape with area 4, what is the area at step 3?
- 6
- 8
- 9 (Correct answer)
- 12
Correct answer: 9
Step 2: 4 × 1.5 = 6; Step 3: 6 × 1.5 = 9.
Question 3: A code uses a symbol for each number: ★=1, ✦=2, ●=3. What does ✦★ represent?
- 12
- 21 (Correct answer)
- 3
- 23
Correct answer: 21
✦=2 in the tens place and ★=1 in the ones place gives 21.
Question 4: A pattern shows that each square's value equals the sum of the two squares directly above it. The top row is 1, 2, 3. What is the value of the leftmost square in row 2?
- 1
- 2
- 3 (Correct answer)
- 4
Correct answer: 3
The leftmost square in row 2 is the sum of the first two squares above it: 1 + 2 = 3.
Question 5: In a sequence of figures, the number of sides increases by 1 and the color alternates between black and white. Figure 1 is a black triangle. What is figure 4?
- Black hexagon
- White hexagon (Correct answer)
- Black pentagon
- White hexagon
Correct answer: White hexagon
Figure 4 has 3 + 3 = 6 sides (hexagon) and alternates to white (odd=black, even=white).
Question 6: A sequence: 100, 50, 25, 12.5, ___. What comes next?
- 6
- 6.25 (Correct answer)
- 7.5
- 10
Correct answer: 6.25
Each term is halved: 12.5 ÷ 2 = 6.25.
Question 7: In a pattern matrix, every shape in the right column is the combination of shapes in the left and middle columns. Left: circle, Middle: square, Right: ___.
- Triangle
- Circle inside a square (Correct answer)
- Larger circle
- Square only
Correct answer: Circle inside a square
The right column combines (overlaps) the left and middle shapes, producing a circle inside a square.
