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.)

The correct answer is

RTP

Find the gaps between consecutive letters in each cluster using their alphabet positions.

EHB: E(5)→H(8) is +3, H(8)→B(2) is −6.

KNH: K(11)→N(14) is +3, N(14)→H(8) is −6.

ORL: O(15)→R(18) is +3, R(18)→L(12) is −6.

So three clusters follow the pattern +3 then −6, while RTP: R(18)→T(20) is +2, T(20)→P(16) is −4, which is different.

Hence, the letter-cluster that does not belong to the group is RTP.
