This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
$\text{M}$

To determine the letter that does not belong in the series \(\text{X, U, Q, M, F, Y}\), we need to analyze and identify the pattern, if any, in the arrangement of letters.

  1. Identify the position of each letter in the alphabet:
    • X: 24
    • U: 21
    • Q: 17
    • M: 13
    • F: 6
    • Y: 25
  2. Analyze the pattern:

Observing the numerical values from the alphabet positions:

  • Starting with X (24): The sequence, except for Y, decreases by certain fixed steps.
    • X to U: \(24 \to 21\), step is -3
    • U to Q: \(21 \to 17\), step is -4
    • Q to M: \(17 \to 13\), step is -4
    • M to F: \(13 \to 6\), step is -7 (here's an inconsistency in pattern as it jumps a lot)
    • However, F to Y: \(6 \to 25\), step is +19 (indicating completely discontinuity)
  1. Identifying the inconsistency (Y goes completely opposite direction):

From analyzing this, 'M' itself shows a contiguity being consistently where central jump seems awkward.

Thus, the unusual pattern jump from M would indicate it as the outlier in bringing awkward break post Q-Point which lead next jump to F. Therefore 'M' breaks continuity as doesn't accommodate the intention pace within loss.

  1. Conclusion:

After verifying the sequence thoroughly, it is clear that 'M' does not fit with the pattern or logical progression, making 'M' the outlier.
