Analyze the pattern for each of the three positions across the series independently: 1st letter +19 or -7, 2nd letter -7, 3rd letter +12.
Analyze the pattern for each of the three positions across the series independently: 1st letter +19 or -7, 2nd letter -7, 3rd letter +12.
Analyze 1st Letters
G(7) - 7 = 26(Z); Z(26) - 7 = 19(S); S(19) - 7 = 12(L); L(12) - 7 = 5(E).
Analyze 2nd Letters
T(20) - 7 = 13(M); M(13) - 7 = 6(F); F(6) - 7 = -1 => 25(Y); Y(25) - 7 = 18(R).
Analyze 3rd Letters
N(14) - 7 = 7(G); G(7) - 7 = 26(Z); Z(26) - 7 = 19(S); S(19) - 7 = 12(L).
A: RDS is incorrect because the pattern yields ERL. C: ERF is incorrect because the 3rd letter is L, not F. D: ERD is incorrect because the 3rd letter is L, not D.
B is correct because each letter in the triplets GTN, ZMG, SFZ, and LYS shifts back by 7 positions in the English alphabet (A=1, B=2...Z=26).
For alphabetical series, always convert letters to their numerical positions (A=1, Z=26) immediately to simplify finding the common difference.
