GCAT Number and Letter Sequences 2 — Questions and Answers
Question 1: What comes next in the sequence? 3, 6, 12, 24, 48, ___
- 72
- 84
- 96 (Correct answer)
- 72
Correct answer: 96
Each term is doubled, so 48 × 2 = 96.
Question 2: Which letter comes next? D, G, J, M, ___
- N
- O
- P (Correct answer)
- Q
Correct answer: P
Each letter advances by 3 positions in the alphabet, so M + 3 = P.
Question 3: What is the missing number? 100, 91, 82, 73, ___, 55
- 62
- 63
- 64 (Correct answer)
- 65
Correct answer: 64
The sequence decreases by 9 each time, so 73 − 9 = 64.
Question 4: Which completes the sequence? Z, X, V, T, ___
- Q
- R (Correct answer)
- S
- P
Correct answer: R
Each letter moves back 2 positions in the alphabet, so T − 2 = R.
Question 5: What is the next number? 1, 4, 9, 16, 25, ___
- 30
- 34
- 36 (Correct answer)
- 49
Correct answer: 36
These are perfect squares (1², 2², 3², 4², 5²), so the next is 6² = 36.
Question 6: Find the next pair: AB, DE, GH, JK, ___
- LM
- MN (Correct answer)
- NM
- NO
Correct answer: MN
Each pair starts 3 letters after the previous pair's start, so after JK comes MN.
