Three of the following four letter-clusters are alike in a certain way and one is different. Pick the letter-cluster that is different from the rest.
Answer & explanation
Correct answer: option 3
THE LOGIC;
1) DWHS,
D → (+4) → H
W → (-4) → S
2) HSLO,
H → (+4) → L
S → (-4) → O
3) MNPK,
M → (+3) → P
N → (-3) → K
4) RIVE,
R → (+4) → V
I → (-4) → E
Thus, MNPK is odd one.
