Letter Series - Solved Questions and Answers

A letter series is a sequence of letters that follows a specific logical pattern or rule. These sequences are designed to test a person's ability to recognize relationships between letters, predict the next element, or identify missing letters in the series.

Letter Series questions and answers are provided below for you to learn and practice.

Question 1: SCD, TEF, UGH, ___, WKL

a) CMN

b) UJI

c) VIJ

d) IJT

Answer: (c) VIJ

Explanation:

In this letter series, each letter is shifted one position forward in the English alphabet. Starting with "SCD," we have:

S + 1 = T

C + 1 = D

D + 1 = E

Continuing this pattern:

U + 1 = V

G + 1 = H

So, the missing term is "VIJ."

Question 2: B2CD, ____, BCD4, B5CD, BC6D

a) B2C2D

b) BC3D

c) B2C3D

d) BCD7

Answer: (c) BC3D

Explanation:

In this letter and number series, the pattern is as follows:

The letter "B" appears at the beginning of each term.

The number represents a sequential count starting from 2 and increasing by 1 with each term.

The letters "C" and "D" appear in each term.

So, the missing term would be "BC3D" as it continues the pattern.

Question 3: DFH, HJL, LNP, ___, TVX

a) DTV

b) NRT

c) PRT

d) RQS

Answer: (c) PRT

Explanation:

In this letter series, each letter is shifted two positions forward in the English alphabet, and the next letter is added. Starting with "DFH," we have:

D + 2 = F

F + 2 = H

H + 2 = J

Continuing this pattern:

P + 2 = R

R + 2 = T

So, the missing term is "PRT."

Question 4: ACE, GIK, MOQ, ___, UYK

a) ACG

b) SUW

c) EIS

d) OPS

Answer: (b) SUW

Explanation:

In this letter series, each letter is shifted two positions forward in the English alphabet, and the next letter is subtracted. Starting with "ACE," we have:

A + 2 = C

C + 2 = E

E + 2 = G

Continuing this pattern:

Q + 2 = S

S + 2 = U

U + 2 = W

So, the missing term is "SUW"

Question 5: BDF, FHJ, JLN, ___, PTV

a) NMN

b) NMO

c) NPR

d) OPM

Answer: (c) NPR

Explanation:

In this letter series, each letter is shifted three positions forward in the English alphabet, and the next letter is added. Starting with "BDF," we have:

B + 4 = F

D + 4 = H

F + 4 = J

Continuing this pattern:

J + 4 = N

L + 4 = P

N + 4 = R

So, the missing term is "NPR."

Question 6: CMM, EOO, GQQ, _____, KUU

a) GRR

b) GSS

c) ISS

d) ITT

Answer: (c) ISS

Explanation:

The pattern follows +2 steps for each letter:

First letters: C → E → G → I → K

Second letters: M → O → Q → S → U

Third letters: M → O → Q → S → U

The missing term is ISS.

Question 7: ACE, BDF, CEG, DFH, ___

a) HMP

b) JOM

c) EGI

d) JMN

Answer: (C) EGI

Explanation:

In this letter series, each letter is shifted one position forward in the English alphabet, and the next letter is skipped. Starting with "ACE," we have:

A + 1 = B

C, D, E

E + 1 = F

G, H, I,

D + 1 = E

Continuing this pattern:

F + 1 = G

So, the missing term is "EGI"

Question 8: PQ, RS, UV, XY, __

a) AC

b) ZA

c) AB

d) BC

Answer: (b) ZA

Explanation:

In this letter series, each pair of letters represents consecutive letters in the English alphabet. Starting with "PQ," we have:

P, Q

R, S

U, V

X, Y

Continuing this pattern:

Z, A

So, the missing term is "ZA," representing consecutive letters in the English alphabet.

Question 9: KL, MN, OP, RS, __

a) VW

b) YZ

c) WX

d) XT

Answer: (a) VW

Explanation:

In this letter series, each pair of letters represents consecutive letters in the English alphabet. Starting with "KL," we have:
