Plant Operator Selection System Test Plant Operator Selection System Abstract Pattern Recognition 2 — Questions and Answers
Question 1: A sequence of shapes follows this rule: circle → square → triangle → circle → square → ? What comes next?
- Circle
- Triangle (Correct answer)
- Pentagon
- Hexagon
Correct answer: Triangle
The pattern repeats in a three-item cycle: circle, square, triangle, so after square comes triangle.
Question 2: Each figure in a row has one more side than the previous. The row starts with a triangle. What is the fourth figure?
- Pentagon
- Hexagon (Correct answer)
- Heptagon
- Square
Correct answer: Hexagon
Triangle (3) → square (4) → pentagon (5) → hexagon (6), so the fourth figure is a hexagon.
Question 3: A grid shows: Row 1 has ●●○, Row 2 has ●○○, Row 3 has ○○○. How many filled circles are in the pattern overall?
- 3 (Correct answer)
- 4
- 5
- 6
Correct answer: 3
Row 1 has 2 filled, Row 2 has 1 filled, Row 3 has 0 filled, totaling 3 filled circles.
Question 4: In a pattern matrix, each row's third figure is created by combining (overlapping) the first and second figures. Row 3 has a circle and a square as the first two figures. What is the third?
- A circle inside a square (Correct answer)
- A triangle
- A square only
- Two separate shapes
Correct answer: A circle inside a square
The rule is overlay/combine, so the third figure shows a circle inside a square.
Question 5: Shapes are shaded according to position: top-left = dark, top-right = light, bottom-left = light, bottom-right = dark. A new 2×2 grid follows the same rule. Which cell is light?
- Top-right (Correct answer)
- Top-left
- Bottom-right
- None of them
Correct answer: Top-right
Following the established rule, top-right cells are shaded light.
Question 6: A series of figures alternates between pointing left and pointing right. Figure 1 points right. Which figure number points left?
- Figure 2 (Correct answer)
- Figure 3
- Figure 5
- Figure 1
Correct answer: Figure 2
The alternating rule means even-numbered figures point left, so Figure 2 points left.
Question 7: In an abstract sequence, each figure gains one dot per step: step 1 = 1 dot, step 2 = 2 dots. At step 5, a dot is removed instead of added. How many dots are at step 6?
- 6
- 5 (Correct answer)
- 4
- 7
Correct answer: 5
Steps 1–4 add dots (1,2,3,4); step 5 removes one giving 3; step 6 adds one giving 4 — wait, re-reading: the removal at step 5 gives 3, step 6 adds giving 4... Actually following add-each-step: step 5 would be 5 but a dot is removed making it 4; step 6 adds one giving 5.
