AON Abstract Reasoning 2 — Questions and Answers
Question 1: Which number does NOT belong in the group: 4, 9, 16, 25, 35, 49?
- 9
- 16
- 25
- 35 (Correct answer)
Correct answer: 35
All others are perfect squares (4=2², 9=3², 16=4², 25=5², 49=7²); 35 is not a perfect square.
Question 2: Complete the analogy: Circle is to Sphere as Square is to ___.
- Cube (Correct answer)
- Cone
- Cylinder
- Rectangle
Correct answer: Cube
A circle is the 2D version of a sphere; similarly, a square is the 2D version of a cube.
Question 3: A pattern alternates: +3, ×2, +3, ×2. Starting at 1: 1, 4, 8, 11, 22, ___. What is the next number?
- 25 (Correct answer)
- 26
- 44
- 33
Correct answer: 25
After 22, the next operation is +3: 22 + 3 = 25.
Question 4: Which figure completes the pattern: Each row contains a triangle, a circle, and a square. Row 1: triangle, circle, square. Row 2: circle, square, triangle. Row 3: square, triangle, ___.
- Triangle
- Square
- Circle (Correct answer)
- Pentagon
Correct answer: Circle
Each shape appears exactly once per row in a rotating order; Row 3 is missing the circle.
Question 5: Find the odd one out: 121, 144, 169, 180, 196.
- 121
- 144
- 169
- 180 (Correct answer)
Correct answer: 180
121=11², 144=12², 169=13², 196=14² are all perfect squares; 180 is not.
Question 6: In the sequence 1, 1, 2, 3, 5, 8, 13, ___, what is the missing number?
- 18
- 20
- 21 (Correct answer)
- 23
Correct answer: 21
This is the Fibonacci sequence where each term equals the sum of the two preceding terms: 8 + 13 = 21.
