Question

Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster DOES NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

• A. EDH
• B. TTW
• C. QPT
• D. ZYC

Answer 1

Answer:

B. TTW

Let’s check the alphabet positions of each letter.

(A=1, B=2, … Z=26)

EDH

E = 5
D = 4
H = 8

Pattern:
5 → 4 (−1)
4 → 8 (+4)

So pattern = −1, +4

TTW

T = 20
T = 20
W = 23

Pattern:
20 → 20 (0)
20 → 23 (+3)

Pattern = 0, +3

QPT

Q = 17
P = 16
T = 20

Pattern:
17 → 16 (−1)
16 → 20 (+4)

Pattern = −1, +4

ZYC

Z = 26
Y = 25
C = 3

Pattern:
26 → 25 (−1)
25 → 3

Since after Z it cycles back to A:

25 → 26 → 1 → 2 → 3
That is +4

So pattern = −1, +4

Observation

• EDH → −1, +4

• QPT → −1, +4

• ZYC → −1, +4

• TTW → 0, +3 different

TTW does NOT belong to the group.
