Analyze the pattern for each of the three positions across the sequence separately: the first letters decrease by 2, the middle letters increase by 3, and the last letters decrease by 2.
Analyze the pattern for each of the three positions across the sequence separately: the first letters decrease by 2, the middle letters increase by 3, and the last letters decrease by 2.
First Letter Pattern
Q(17) → O(15) → M(13) → K(11) → I(9). Each step is -2.
Second Letter Pattern
G(7) → F(6) → E(5) → D(4) → C(3). Each step is -1.
Third Letter Pattern
Y(25) → W(23) → U(21) → S(19) → Q(17). Each step is -2.
A: IDQ is wrong as the last letter is Q, not U; B: ICR is wrong because the third letter must be Q; C: IDR is wrong because the second letter is C and the third is Q.
D is correct because the series follows a constant decrement of -2, -1, -2 for the three positions in each triplet respectively (Q-2=I, G-1=C, Y-2=Q).
For alphabetical series, always break the term into individual character streams (1st, 2nd, 3rd) and map their numeric values (A=1, B=2,... Z=26) to identify the gap constants quickly.
