Q1): Find the next letter in the series: A, C, E, G, ?
A) H
B) I
C) J
D) K
Answer: B) I
Explanation: Write positions: A=1, C=3, E=5, G=7. The pattern is +2 each time (1→3→5→7). Next position is 7+2=9, and 9th letter is I.
Q2): Find the next letter in the series: B, E, H, K, ?
A) L
B) M
C) N
D) O
Answer: C) N
Explanation: Positions: B=2, E=5, H=8, K=11. Each step is +3 (2→5→8→11). Next is 11+3=14, and the 14th letter is N.
Q3): Find the next letter in the series: Z, X, V, T, ?
A) S
B) R
C) Q
D) P
Answer: B) R
Explanation: Positions: Z=26, X=24, V=22, T=20. The pattern is −2 each time (26→24→22→20). Next is 20−2=18, and 18th letter is R.
Q4): Find the missing letter in the series: A, Z, B, Y, C, X, ?
A) D
B) W
C) V
D) E
Answer: A) D
Explanation: The series takes one letter from the start, then one from the end: A (start), Z (end), B (start), Y (end), C (start), X (end). Next should be the next start letter after C, which is D.
Q5): Find the next letter in the series: A, C, F, J, ?
A) M
B) N
C) O
D) P
Answer: C) O
Explanation: Positions: A=1, C=3 (+2), F=6 (+3), J=10 (+4). The jump increases by 1 each time. Next jump is +5, so 10+5=15. The 15th letter is O.
Q6): Find the next letter in the series: D, G, K, P, ?
A) T
B) U
C) V
D) W
Answer: C) V
Explanation: Positions: D=4, G=7 (+3), K=11 (+4), P=16 (+5). The jumps are +3, +4, +5, so next is +6. Therefore 16+6=22, and 22nd letter is V.
Q7): Find the next letter in the series: V, S, P, M, ?
A) K
B) J
C) I
D) H
Answer: B) J
Explanation: Positions: V=22, S=19, P=16, M=13. Each step is −3 (22→19→16→13). Next is 13−3=10, and 10th letter is J.
Q8): Find the missing letter in the series: L, N, ?, R, T
A) O
B) P
C) Q
D) S
Answer: B) P
Explanation: Positions: L=12, N=14, R=18, T=20. This looks like +2 steps: 12, 14, 16, 18, 20. The missing position is 16, which is P.
Q9): Find the next letter in the series: A, B, C, E, F, G, ?
A) H
B) I
C) D
D) J
Answer: B) I
Explanation: The letters are in groups of three, and one letter is skipped after each group: A B C (skip D), E F G (skip H), then the next group starts with I. So the next letter is I.
Q10): Find the next letter in the series: M, L, N, K, O, J, ?
A) I
B) P
C) Q
D) H
Answer: B) P
Explanation: This is two patterns mixed: one pattern increases (M, N, O, …) and the other decreases (L, K, J, …). The sequence alternates: M (up), L (down), N (up), K (down), O (up), J (down). Next should be the next “up” letter after O, which is P.
Q11): Find the next letter in the series: E, D, F, E, G, F, ?
A) G
B) H
C) E
D) D
Answer: B) H
Explanation: Look in pairs: (E, D), (F, E), (G, F). In each pair, the first letter increases by 1 (E→F→G), and the second letter also increases by 1 (D→E→F). So the next first letter should be H.
Q12): Find the next letter in the series: P, R, S, U, V, ?
A) W
B) X
C) Y
D) Z
Answer: B) X
Explanation: Positions: P=16 to R=18 is +2, R=18 to S=19 is +1. Then S=19 to U=21 is +2, U=21 to V=22 is +1. The pattern repeats (+2, +1). Next should be +2 from V (22+2=24), and 24th letter is X.
Q13): Find the next letter in the series: H, K, O, T, ?
A) X
B) Y
C) Z
D) W
Answer: C) Z
Explanation: Positions: H=8, K=11 (+3), O=15 (+4), T=20 (+5). The jumps are +3, +4, +5, so next jump is +6. Thus 20+6=26, and 26th letter is Z.
Q14): Find the next letter in the series: B, D, H, N, ?
A) S
B) T
C) U
D) V
Answer: D) V
Explanation: Positions: B=2, D=4 (+2), H=8 (+4), N=14 (+6). The jumps increase by 2 each time: +2, +4, +6, so next is +8. Therefore 14+8=22, and the 22nd letter is V.
Q15): Find the missing letter in the series: S, O, K, ?, C
A) H
B) G
C) F
D) E
Answer: B) G
Explanation: Positions: S=19, O=15, K=11. Each step is −4 (19→15→11). Continue: 11−4=7, which is G. Then G=7 to C=3 is also −4, so the pattern matches.
Q16): Find the next letter in the series: A, B, D, E, G, H, ?
A) I
B) J
C) K
D) L
Answer: B) J
Explanation: Positions: A=1 to B=2 is +1, B=2 to D=4 is +2, D=4 to E=5 is +1, E=5 to G=7 is +2, G=7 to H=8 is +1. The pattern alternates +1, +2. Next should be +2 from H: 8+2=10, which is J.
Q17): Find the next letter in the series: D, H, L, P, ?
A) Q
B) R
C) S
D) T
Answer: D) T
Explanation: Positions: D=4, H=8, L=12, P=16. Each time it increases by +4. Next is 16+4=20, and the 20th letter is T.
Q18): Find the next letter in the series: G, I, L, P, ?
A) S
B) T
C) U
D) V
Answer: C) U
Explanation: Positions: G=7 to I=9 is +2, I=9 to L=12 is +3, L=12 to P=16 is +4. The jump increases by 1 each time, so next jump is +5. Therefore 16+5=21, which is U.
Q19): Find the next letter in the series: A, E, I, M, ?
A) N
B) O
C) P
D) Q
Answer: B) O
Explanation: Positions: A=1, E=5, I=9, M=13. Each step is +4 (1→5→9→13). Next is 13+4=17, and 17th letter is Q.
But wait, 17th letter is Q, not O. Let us re-check: A(1), E(5), I(9), M(13). Yes, +4 each time. Next is 17 = Q.
So the correct option should match Q. Among the options, Q is not present, so the options must be corrected to include Q. The correct next letter is Q.
Answer: D) Q
Explanation: Positions: A=1, E=5, I=9, M=13. The pattern is +4 each time. Next is 13+4=17, and the 17th letter is Q.
Q20): Find the next letter in the series: A, D, H, M, ?
A) Q
B) R
C) S
D) T
Answer: C) S
Explanation: Positions: A=1 to D=4 is +3, D=4 to H=8 is +4, H=8 to M=13 is +5. The jump increases by 1 each step, so next jump is +6. Thus 13+6=19, and the 19th letter is S.
