RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
X82Q

To solve the problem of identifying the pattern in the given series, we will analyze each component of the series separately: the letter, the number, and the ending letter. Based on the series: 
L34E, O46H, R58K, U70N, ?

  1. Letter Pattern: The first letter of each term follows a pattern with a difference of +3.
    • L (12th letter of the alphabet), O (15th), R (18th), U (21st).
    • Continuing this pattern, the next letter should be X (24th letter of the alphabet).
  2. Number Pattern: Here, the sequence of numbers increases by 12.
    • 34, 46, 58, 70.
    • Adding 12 to 70 gives us 82.
  3. Ending Letter Pattern: The ending letter follows a pattern where each letter is +3 alphabet positions from the previous term.
    • E (5th letter), H (8th), K (11th), N (14th).
    • Adding 3 to 14 gives us 17, which corresponds to Q.

By combining the patterns identified in each component, the term that should follow in the series is X82Q.

Therefore, the correct option is X82Q.
