Which of the following options should come in place of the question mark (?) in the given series based on the English alphabetical order? FJN, IMQ, LPT, OSW,?
SUY
RVZ
RUY
RUZ
RVZ
Observe the first letters of the triplets: F(6), I(9), L(12), O(15) follow a +3 pattern. The next letter must be 15 + 3 = 18 (R). Only Option B starts with R.
Observe the first letters of the triplets: F(6), I(9), L(12), O(15) follow a +3 pattern. The next letter must be 15 + 3 = 18 (R). Only Option B starts with R.
Analyze the first letters
F(6), I(9), L(12), O(15). Pattern is +3. Next is 15 + 3 = 18, which is R.
Analyze the second letters
J(10), M(13), P(16), S(19). Pattern is +3. Next is 19 + 3 = 22, which is V.
Analyze the third letters
N(14), Q(17), T(20), W(23). Pattern is +3. Next is 23 + 3 = 26, which is Z.
Formulate the final term
Combining the results: R (18), V (22), Z (26). The final term is RVZ.
A: SUY uses different starting letters (+3/4 instead of +3), C: RUY ends in Y (25) instead of Z (26), D: RUZ starts with R but the second letter U is incorrect.
B is correct because the series follows a consistent +3 pattern for each character in the triplets, resulting in R(18), V(22), Z(26) for the final term.
For letter series, always write down the numerical position (A=1, B=2, ..., Z=26) first; this turns visual pattern recognition into simple arithmetic.
