Explanation

The sequence 102, 101, 98, 93, 86, 74, 66, 53 follows a pattern where the difference between consecutive terms decreases by 2 each time: 102-101=1, 101-98=3, 98-93=5, 93-86=7, 86-74=12 (should be 9), 74-66=8 (should be 11), 66-53=13. The pattern should be differences of 1, 3, 5, 7, 9, 11, 13. This would make 86-9=77, not 74. Therefore 74 is the wrong number.
