Which of the following letter-clusters does not belong to the group: (A) BDF, (B) HJL, (C) NPR, (D) TWY?
BDF
HJL
NPR
TWY
TWY
Observe the constant jump of +2 between consecutive letters in the alphabet for three of the options, while checking for a deviation in the fourth.
Observe the constant jump of +2 between consecutive letters in the alphabet for three of the options, while checking for a deviation in the fourth.
Analyze the alphabetical gap for BDF
B is 2, D is 4, F is 6. The pattern is +2, +2.
Analyze the alphabetical gap for HJL, NPR, and TWY
H(8), J(10), L(12) follows +2, +2. N(14), P(16), R(18) follows +2, +2. T(20), W(23), Y(25) follows +3, +2.
A: BDF follows a consistent +2 gap; B: HJL follows a consistent +2 gap; C: NPR follows a consistent +2 gap.
D is correct because TWY follows a pattern of +3, +2, while all other clusters strictly follow a +2, +2 pattern.
Always convert letters to their numerical positions (A=1, B=2... Z=26) first to identify arithmetic differences between clusters.
