A sequence of letters is given below in a specific order. Identify the correct sequence from the given alternatives.
UP-SN-RQ
TP-SO-RQ
UP-SO-RT
TP-SN-RT
TP-SO-RQ
In each pair, the first letter shifts by -1 and the second letter shifts by -1, then the groups themselves follow a specific sequential pattern where the next triad starts where the previous one ends or by consistent subtraction.
In each pair, the first letter shifts by -1 and the second letter shifts by -1, then the groups themselves follow a specific sequential pattern where the next triad starts where the previous one ends or by consistent subtraction.
Analyze the pattern
Given triads: LH-KG-JI and VR-UQ-TS. Mapping: L(12)H(8) тЖТ K(11)G(7) тЖТ J(10)I(9). Each pair within the triad is decreasing by -1 for each letter: L-1=K, H-1=G; K-1=J, G-1=F (Note: I is mentioned in the prompt pattern sequence).
Apply to options
Looking at Option B: TP-SO-RQ. T(20)P(16) тЖТ S(19)O(15) тЖТ R(18)Q(17). The transition between letters matches the logic of consecutive decrements found in the sequence.
A: UP-SN-RQ has inconsistent letter gaps. C: UP-SO-RT does not follow the continuous decrement pattern. D: TP-SN-RT does not follow the consistent -1 shift for all pairs.
B is correct because the triad TP-SO-RQ maintains the consistent alphabetical decrement pattern observed in the given examples.
In letter triad questions, always write the numerical rank of letters (A=1, B=2...) to identify the arithmetic difference quickly.
