Explanation

The series follows the pattern: add previous difference + increasing offset. Differences are -6, -3, +2, +11, +28. The pattern in differences is +3, +5, +9, +17 (gaps doubling: 2, 4, 8). Expected next difference: +17+16=33, giving 76+33=109. But the series has 135, which breaks this pattern. Alternative: (n-1)+(n-2)+k where k increases. 37+35=72 needs +10 to get 82, not 76. 135 is clearly wrong.
