Which of the following options should come in place of the question mark (?) in the given series based on the English alphabetical order? DBL, IEN, NHP, SKR,?
XNT
YMT
YNT
SMX
XNT
Look at each position in the triplet separately. The 1st letter jumps +5, the 2nd +5, and the 3rd +2 consistently.
Look at each position in the triplet separately. The 1st letter jumps +5, the 2nd +5, and the 3rd +2 consistently.
Analyze 1st Letters
D(4), I(9), N(14), S(19). Pattern is +5. Next letter is 19 + 5 = 24 (X).
Analyze 2nd Letters
B(2), E(5), H(8), K(11). Pattern is +3. Next letter is 11 + 3 = 14 (N).
Analyze 3rd Letters
L(12), N(14), P(16), R(18). Pattern is +2. Next letter is 18 + 2 = 20 (T).
B: YMT corresponds to +5, +8, +2 which is incorrect. C: YNT is incorrect because the first letter follows a +5 pattern. D: SMX is incorrect as the sequence does not maintain the arithmetic progression.
A is correct because the series follows a consistent pattern of +5 for the first letter, +3 for the second letter, and +2 for the third letter, resulting in XNT.
Always convert letters to their numerical positions (A=1, B=2, ..., Z=26) immediately to identify hidden arithmetic patterns faster.
