Find the odd letter group: CHM, HMR, DIN, LPU.

ACHM

Correct answer: (D) LPU

Explanation

LPU is the odd group.

In CHM, HMR and DIN each step is +5.

CHM: 3, 8, 13; HMR: 8, 13, 18; DIN: 4, 9, 14 all move +5, +5.

L, P, U are 12, 16, 21, moving +4 then +5.

So the group with an uneven step stands apart.
