Correct answer: B

Pattern: each number appears twice, then 13 is subtracted to get the next distinct number.

  • Step 1: 53 appears twice.

  • Step 2: Subtract 13 from 53 to get 40, so 40 appears twice (53 - 13 = 40).

  • Step 3: Subtract 13 from 40 to get 27, so 27 appears twice (40 - 13 = 27).

  • Step 4: Subtract 13 from 27 to get 14, so the next number is 14 (27 - 13 = 14).

Answer: 14
