RBC Abstract and Logical Patterns 5 — Questions and Answers
Question 1: A figure alternates: small dark, large light, small dark, large light, ___. What is the 7th figure?
- Large light
- Small dark (Correct answer)
- Large dark
- Small light
Correct answer: Small dark
The two-item cycle means odd positions are small dark and even positions are large light; position 7 is odd, so small dark.
Question 2: In a number pattern, the difference between consecutive terms doubles each time: differences are 1, 2, 4, 8. If the first term is 3, what is the 5th term?
- 18 (Correct answer)
- 17
- 16
- 20
Correct answer: 18
3 + 1 = 4, 4 + 2 = 6, 6 + 4 = 10, 10 + 8 = 18.
Question 3: A symbol table shows: ★ = 5, ♦ = 3, ●= 2. The expression ★ + ♦ × ● equals ___.
- 16
- 11 (Correct answer)
- 13
- 10
Correct answer: 11
Following order of operations: ♦ × ● = 3 × 2 = 6, then ★ + 6 = 5 + 6 = 11.
Question 4: A grid pattern: each cell in column 2 is double the corresponding cell in column 1. Column 1 values are 3, 5, 7. What is the sum of all column 2 values?
- 30 (Correct answer)
- 15
- 20
- 25
Correct answer: 30
Column 2: 6, 10, 14; sum = 30.
Question 5: An analogy: 3 is to 9 as 5 is to ___.
- 10
- 15
- 25 (Correct answer)
- 20
Correct answer: 25
The rule is squaring: 3² = 9 and 5² = 25.
Question 6: In a visual matrix, each row contains exactly one each of three symbols (▲, ■, ●). The first row is ▲-■-●, the second row is ■-●-▲. What is the third row?
- ●-▲-■ (Correct answer)
- ▲-■-●
- ■-▲-●
- ●-■-▲
Correct answer: ●-▲-■
Each symbol rotates one position left per row; the third row must be ●-▲-■ so every column contains all three symbols.
Question 7: A sequence of figures shows a triangle inside a circle inside a square. The next figure removes the outermost shape. What does the figure after that show?
- Only a triangle (Correct answer)
- Only a circle
- Circle inside a square
- Triangle inside a square
Correct answer: Only a triangle
Removing square leaves circle+triangle; removing circle (the new outermost) leaves only the triangle.
