XFG
YGH
ZDI
XHJ
XFG
Observe the first, second, and third letters of each triplet separately; each undergoes a consistent constant jump (+3, +26/-26, +1).
Observe the first, second, and third letters of each triplet separately; each undergoes a consistent constant jump (+3, +26/-26, +1).
Analyze the first letters of each triplet
L (12) → O (15) → R (18) → U (21). The pattern is +3. So, U (21) + 3 = 24, which is X.
Analyze the second letters of each triplet
X (24) → Z (26) → B (2) → D (4). The pattern is +2. So, D (4) + 2 = 6, which is F.
Analyze the third letters of each triplet
C (3) → D (4) → E (5) → F (6). The pattern is +1. So, F (6) + 1 = 7, which is G.
B: Starts with Y instead of X; C: Starts with Z instead of X; D: Starts with X but second and third letters are HJ instead of FG.
A is correct because the series follows a fixed pattern where the first letter increments by 3, the second by 2, and the third by 1, resulting in XFG.
For alphabetical series, always convert letters to their numerical positions (A=1, Z=26) to visualize the addition/subtraction patterns clearly.
