Which of the following options should come in place of the question mark (?) in the given series based on the English alphabetical order? MPL, ORN, QTP, SVR,?
UXT
XTU
UTX
XUT
UXT
Look at the first letter of each triplet; they follow a +2 sequence. M(+2)=O, O(+2)=Q, Q(+2)=S, S(+2)=U. Since only one option starts with U, you can immediately identify it.
Look at the first letter of each triplet; they follow a +2 sequence. M(+2)=O, O(+2)=Q, Q(+2)=S, S(+2)=U. Since only one option starts with U, you can immediately identify it.
Analyze the first letters
The first letters are M(13), O(15), Q(17), S(19). The pattern is +2. Therefore, 19 + 2 = 21, which corresponds to the letter U.
Analyze the second letters
The second letters are P(16), R(18), T(20), V(22). The pattern is +2. Therefore, 22 + 2 = 24, which corresponds to the letter X.
Analyze the third letters
The third letters are L(12), N(14), P(16), R(18). The pattern is +2. Therefore, 18 + 2 = 20, which corresponds to the letter T.
Final Combination
Combining these gives the final term: U, X, T, which is UXT.
B: XTU does not follow the +2 pattern for each position; C: UTX places the middle and last letters in the wrong order; D: XUT starts with X instead of U.
A is correct because the series follows a consistent +2 increment for every letter in the triplet, resulting in UXT.
When solving letter series, check the first letter of the next term first—it often eliminates 2-3 wrong options instantly, saving valuable time.
