Last Updated : 20 Aug, 2025

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:

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
