Predecessor & Successor

To find the predecessor & successor of the given number we have to find just before the number & after the number of the given number respectively. Suppose there is a number given which is ‘n’, and if wish to find the Successor and predecessor of said number ‘n’ then the Successor number would be (n + 1) and predecessor number would be (n – 1). As an example, if n = 125, then predecessor would be 125 – 1 = 124, and successor number would be 125 + 1 = 126. There are some more examples are given below-
