Question 1: What number completes the pattern: 5, 10, 20, 40, 80, ?
- 140
- 150
- 160 (Correct answer)
- 120
Correct answer: 160

- 240
- 360
- 600
- 720 (Correct answer)
Correct answer: 720
Each term is multiplied by successive integers (×1, ×2, ×3, ×4, ×5, ×6), so 120 × 6 = 720.
Question 3: Which number is missing: 3, 9, 27, 81, ?
- 162
- 243 (Correct answer)
- 324
- 729
Correct answer: 243
Each term is multiplied by 3, so 81 × 3 = 243.
Question 4: What comes next: 50, 48, 44, 38, 30, ?
- 18
- 20 (Correct answer)
- 22
- 25
Correct answer: 20
Differences are 2, 4, 6, 8, 10 — so 30 − 10 = 20.
Question 5: Find the missing number: 2, 3, 5, 8, 13, 21, ?
- 29
