FAST Visual Pattern Recognition — Questions and Answers
Question 1: What number replaces the '?' in the sequence: 2, 6, 18, 54, ?
- 108
- 162 (Correct answer)
- 216
- 270
Correct answer: 162
Each term is multiplied by 3: 2×3=6, 6×3=18, 18×3=54, 54×3=162.
Question 2: A 3×3 matrix has circles in row 1, squares in row 2, and triangles in row 3. Within each row shapes are small, medium, and large from left to right. The bottom-right cell is missing. What should it contain?
- A small triangle
- A medium circle
- A large triangle (Correct answer)
- A large square
Correct answer: A large triangle
Two rules apply simultaneously: the shape must match the row (triangles) and the size must match the column (largest, rightmost). Both rules point to a large triangle.
Question 3: A black dot moves clockwise one position per step around the four corners of a square (top-left → top-right → bottom-right → bottom-left). After top-right, where is the dot?
- Top-left
- Bottom-left
- Bottom-right (Correct answer)
- Centre
Correct answer: Bottom-right
Clockwise from top-right is bottom-right. The sequence is TL → TR → BR → BL → TL and repeats.
Question 4: A symbol sequence reads: ○ △ □ ○ △ □ ○ △ ? — what comes next?
- â—‹
- â–³
- â–¡ (Correct answer)
- â—‡
Correct answer: â–¡
The repeating unit is â—‹ â–³ â–¡ (length 3). Position 9 is the 3rd element of the third cycle, which is â–¡.
Question 5: In a matrix each shape (circle, square, triangle) appears in each shading (black, grey, outline) exactly once per row and once per column. The circle column already contains a black circle (row 1) and a grey circle (row 2). What is in the circle cell of row 3?
- Black circle
- Outline circle (Correct answer)
- Grey triangle
- Black triangle
Correct answer: Outline circle
Each shading must appear exactly once per column. Black and grey are already used in the circle column, so the remaining option is outline circle.
Question 6: The letters A, C, E, G follow a pattern. What letter comes next?
- H
- I (Correct answer)
- J
- K
Correct answer: I
Each letter skips one: A(skip B)C(skip D)E(skip F)G(skip H)I.
