In the sequence of numbers, there is a pattern where the second number is greater than the first by 1, the third is greater than the second by 2, the fourth is greater than the third by 3, then again by 2, by 1, and again by 1 (this seems to have started over). Therefore, it can be continued as follows: 1, 2, 4, 7, 9, 10, 11, 13, 16, 18, 19, 20, 22, 25, 27, 28, 29, 31, 34, 36, 37, 38, 40, 43, 45, 46, 47, 49, 52, 54, 55, 56, 58, 61, 63, 64, 65, 67, 70, 72... 71 does not belong to this sequence.
