Split the term into three independent sub-series: the first letter follows +3, the number follows +3, and the last letter follows +4.
Split the term into three independent sub-series: the first letter follows +3, the number follows +3, and the last letter follows +4.
Analyze the first letters
B(2), E(5), H(8), K(11). Each advances by +3 positions. Therefore, the next letter is 11 + 3 = 14, which corresponds to N.
Analyze the middle numbers
2, 5, 8, 11. Each number increases by +3. Therefore, the next number is 11 + 3 = 14.
Analyze the last letters
D(4), H(8), L(12), P(16). Each letter advances by +4 positions. Therefore, the next letter is 16 + 4 = 20, which corresponds to T.
B: Incorrect because the middle number is 14 but the first letter must be N, not M. C: Incorrect because the middle number should be 14, not 15. D: Incorrect because the first letter is O and the last letter is S, failing the +3 and +4 patterns.
A is correct because the sequence follows a consistent pattern of +3 for the first letter, +3 for the number, and +4 for the last letter, resulting in N14T.
For complex alphanumeric series, always break them into individual components (letters vs numbers) and solve them as separate sequences to avoid confusion.
