GCAT Numerical Series Patterns 4 — Questions and Answers
Question 1: Find the next number: 1, 2, 4, 7, 11, 16, ?
- 20
- 21
- 22 (Correct answer)
- 25
Correct answer: 22
The differences are 1, 2, 3, 4, 5, so the next difference is 6 and 16 + 6 = 22.
Question 2: What comes next: 256, 64, 16, 4, ?
- 0
- 1 (Correct answer)
- 2
- 3
Correct answer: 1
Each term is divided by 4, so 4 ÷ 4 = 1.
Question 3: Complete the sequence: 11, 22, 33, 44, 55, ?
- 60
- 64
- 66 (Correct answer)
- 70
Correct answer: 66
Each term increases by 11, so 55 + 11 = 66.
Question 4: Find the missing term: 0, 1, 8, 27, 64, ?
- 100
- 121
- 125 (Correct answer)
- 144
Correct answer: 125
These are perfect cubes (0³, 1³, 2³, 3³, 4³), so the next is 5³ = 125.
Question 5: What is the next number: 1000, 500, 250, 125, ?
- 50
- 60
- 62.5 (Correct answer)
- 63
Correct answer: 62.5
Each term is halved (divided by 2), so 125 ÷ 2 = 62.5.
Question 6: Complete the series: 2, 3, 5, 8, 12, 17, ?
- 21
- 22
- 23 (Correct answer)
- 24
Correct answer: 23
The differences between terms are 1, 2, 3, 4, 5, 6 — increasing by 1 each time, so 17 + 6 = 23.
Question 7: Find the next term: 5, 25, 125, 625, ?
- 1250
- 2500
- 3125 (Correct answer)
- 5000
Correct answer: 3125
Each term is multiplied by 5, so 625 × 5 = 3125.
