Four letter-clusters have been given, out of which three are alike in some manner and one is different. Select the odd letter-cluster.
Answer & explanation
Correct answer: option 3
THE LOGIC;
1) HGIFJ,
H → (-1) → G → (+2) → I → (-3) → F → (+4) → J
2) DCEBF,
D → (-1) → C → (+2) → E → (-3) → B → (+4) → F
3) TUSVR,
T → (+1) → U → (-2) → S → (+3) → V → (-4) → R
4) RQSPT,
R → (-1) → Q → (+2) → S → (-3) → P → (+4) → T
Thus, TUSVR is the different one.
