Consecutive Integers

​As discussed in the introduction, in Maths, the numbers that follow each other in an order are called consecutive numbers or consecutive integers. These integers go from smallest to the highest, i.e. in ascending order. Some of the examples are: -4,-3,-2, −1, 0, 1, 2, 3, 4. 10,11,12,13,14,15,1
