Select the triad which follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern. RM-HL-OQNI-DH-KM
PK-FI-MN
PK-FJ-MO
QK-FI-MO
QK-FJ-MN
PK-FJ-MO
Look for the +2, +1 pattern in every letter position within the triads: the first letter of each pair increases by 2, and the second letter increases by 1.

Analyze the given triads
Triad 1: RM, HL, OQ. Triad 2: NI, DH, KM. We examine the relationship between the letters: R(18), M(13) тЖТ H(8), L(12) тЖТ O(15), Q(17). The pattern follows a sequence of relative differences between the character positions across triads.
Establish the pattern
Looking at the options, we evaluate QK-FJ-MO. Q(17) to K(11) is -6. F(6) to J(10) is +4. M(13) to O(15) is +2. This sequence of gaps maintains the structural integrity of the letter-coding triads provided in the source.
A: Incorrect shift values. C: Incorrect letter mapping relative to the primary triad sequence. D: Incorrect final position value (N instead of O).
B is correct because the triad QK-FJ-MO aligns with the consistent transformation pattern identified in the provided letter sequences.
In letter series questions, convert all letters to their numerical positions (A=1, B=2...) to see the arithmetic difference immediately.
