Explanation

The series follows n^2 + n: 8^2 + 8 = 72, but 60 doesn't fit. However, examining differences: 144, 169, 196, 228, 253 - not squares. The pattern is actually squared numbers minus a value: 8^2 - 4 = 60, 15^2 - 21 = 204, 20^2 - 27 = 373, 24^2 - 7 = 569, 29^2 - 24 = 797, 33^2 - 59 = 1050. The term 1050 breaks the visible pattern.
