From - 55 (on the basis of the previous number) + 1, - 2, + 3, - 4, + 5, - 6 Get a series of integers: - 54, - 56, - 53, - 57, - 52, - 58 From - 55 (on the basis of the previous number) + 1, - 2, + 3, - 4, + 5, - 6 Get a series of integers: - 54, - 56, - 53, - 57, - 52, - 58 How much larger is the 2013 integer than the 2012 integer? (there must be a calculation process)

+1,-2,+3,-4,+5,-6,… Let n-1 be x, then n = x + n * (- 1) ^ (n + 1) minus n-1 is x + n * (- 1) ^ (n + 1) - x = n * (- 1) ^ (n + 1). In fact, this difference has nothing to do with - 55
