Reasoning — Letter and Alphabet Series — Questions with Answers Open after you finish the quiz — all 10 questions, with answers and explanations.
Q1. What comes next in the series: A, C, E, G, ?
  1. H
  2. I
  3. J
  4. K
Show answer
Answer: B. I
The pattern involves skipping one letter forward each time. A (+2) C (+2) E (+2) G. Following this pattern, G (+2) = I.
Q2. Complete the series: AZ, BY, CX, DW, ?
  1. EV
  2. FU
  3. GT
  4. HS
Show answer
Answer: A. EV
This is a dual series. The first letter of each pair increments alphabetically (A, B, C, D, E). The second letter of each pair decrements alphabetically (Z, Y, X, W, V). Therefore, the next pair is EV.
Q3. Find the missing term: B, D, F, H, ?
  1. I
  2. J
  3. K
  4. L
Show answer
Answer: B. J
Each letter in the series is obtained by skipping one letter forward. B (+2) D (+2) F (+2) H. Following this pattern, H (+2) = J.
Q4. What will come in place of the question mark (?) in the following series? A, C, F, J, O, ?
  1. T
  2. U
  3. V
  4. W
Show answer
Answer: B. U
The pattern of the series is based on the increasing gap between consecutive letters: A to C: +2 (A+2=C) C to F: +3 (C+3=F) F to J: +4 (F+4=J) J to O: +5 (J+5=O) Following this pattern, the next gap should be +6. So, O (+6) = U.
Q5. Choose the correct alternative that will continue the given series: A1, C3, E5, G7, ?
  1. H9
  2. I8
  3. I9
  4. J9
Show answer
Answer: C. I9
This is a combination series of letters and numbers. For letters: A, C, E, G. Each letter skips one letter forward (A+2=C, C+2=E, E+2=G). So, the next letter is G+2 = I. For numbers: 1, 3, 5, 7. Each number increases by 2. So, the next number is 7+2 = 9. Combining these, the next term in the series is I9.
Q6. Identify the next term in the series: ZYX, WVU, TSR, QPO, ?
  1. NML
  2. MNO
  3. LMN
  4. KJI
Show answer
Answer: A. NML
Each term consists of three consecutive letters in reverse alphabetical order. The first letter of each group follows a pattern of decreasing by 3: Z (26) -3 = W (23) W (23) -3 = T (20) T (20) -3 = Q (17) Following this, the next first letter will be Q (17) -3 = N (14). Therefore, the next group of three consecutive letters in reverse alphabetical order starting with N is NML.
Q7. What will come in place of the question mark (?) in the following series? AD, EH, IL, MP, ?
  1. QT
  2. RU
  3. SV
  4. TW
Show answer
Answer: A. QT
This series consists of pairs of letters. We can analyze the pattern for each position independently. For the first letter of each pair: A (+4) E (+4) I (+4) M. Following this, M (+4) = Q. For the second letter of each pair: D (+4) H (+4) L (+4) P. Following this, P (+4) = T. Combining these, the next term in the series is QT.
Q8. Find the next term in the series: B, D, G, K, P, ?
  1. U
  2. V
  3. W
  4. X
Show answer
Answer: B. V
The pattern of the series is based on the increasing gap between consecutive letters: B to D: +2 (B+2=D) D to G: +3 (D+3=G) G to K: +4 (G+4=K) K to P: +5 (K+5=P) Following this pattern, the next gap should be +6. So, P (+6) = V.
Q9. What will come in place of the question mark (?) in the following series? C, F, J, O, U, ?
  1. A
  2. B
  3. C
  4. D
Show answer
Answer: B. B
The pattern of the series involves an increasing gap between consecutive letters, with the alphabet wrapping around from Z to A. C to F: +3 (C+3=F) F to J: +4 (F+4=J) J to O: +5 (J+5=O) O to U: +6 (O+6=U) Following this pattern, the next gap should be +7. U is the 21st letter. U (+7) = 21+7 = 28. Since there are 26 letters in the alphabet, we wrap around: 28 - 26 = 2. The 2nd letter is B. So, U (+7) = B.
Q10. Complete the series: BZA, CXB, DWC, EVD, ?
  1. FWF
  2. FXE
  3. FUE
  4. FZE
Show answer
Answer: C. FUE
This is a three-letter series where each position follows an independent pattern. 1st letter: B, C, D, E. This is a simple increment by 1. So, E (+1) = F. 2nd letter: Z, X, W, V. The pattern is Z (-2) X (-1) W (-1) V. Following this, V (-1) = U. 3rd letter: A, B, C, D. This is a simple increment by 1. So, D (+1) = E. Combining these, the next term in the series is FUE.
