Show answer & explanation
Correct answer: B
Answer: 14
Explanation:
The sequence lists each number twice: 53, 53, 40, 40, 27, 27, ...
Each new pair decreases by 13: 53 − 13 = 40, 40 − 13 = 27.
Therefore the next pair value is 27 − 13 = 14, so the next number is 14.
Thus the correct next number in the series is 14.
