① Continuous odd numbers are expressed as 2n-1,2n + 1,2n + 3 (n belongs to n *)
② Continuous even numbers can be expressed as 2n-2,2n, 2n + 2 (n belongs to n *)
③ Continuous integers can be expressed as n-1, N, N + 1 [n belongs to Z (set of integers)]
Note: the value range of N must be marked
The answer is not unique, according to the requirements of the selection of appropriate expression method can be easy to calculate
