Integers include positive and negative numbers as well as 0. This means -7, -4, 0, 5, 9 and so on are all integers.

Conservative integers are Integers that follow each other sequentially. For example;

2, 3 and 4
-2, -1, 0, 1, 2

In general terms, if the smallest integer in the list is x, then x, x +1, x + 2 are consecutive integers.
