Look at the first letter of each triplet: J(10), L(12), N(14), P(16). It increases by +2, so the next should be R(18). Only option A starts with R.
Look at the first letter of each triplet: J(10), L(12), N(14), P(16). It increases by +2, so the next should be R(18). Only option A starts with R.
Analyze the pattern for the first letter of each triplet
The first letters are J(10), L(12), N(14), P(16). The pattern is +2. Next is 16 + 2 = 18, which is R.
Analyze the pattern for the second letter of each triplet
The second letters are M(13), O(15), Q(17), S(19). The pattern is +2. Next is 19 + 2 = 21, which is U.
Analyze the pattern for the third letter of each triplet
The third letters are P(16), R(18), T(20), V(22). The pattern is +2. Next is 22 + 2 = 24, which is X.
Combine the results
The resulting triplet is R-U-X, which matches Option A.
B: Starts with U, which is incorrect. C: Starts with U, which is incorrect. D: Starts with R, but the sequence following it is XU, which is incorrect.
A is correct because the series follows a consistent +2 pattern for every letter, resulting in RUX.
In alphanumeric series, always break down the complex term into individual letters or numbers and solve them separately for quick results.
