SUCCESSOR AND PREDECESSOR OF INTEGERS
You will be agreeing to know that, the successor of an Integer x is = x + 1
Example.- Successor of 15 is = 15 + 1 = 16
Successor of 33 is 33 + 1 = 34
Successor of 47 is = 47 + 1 = 48
You will be agreeing to know that, the predecessor of an Integer x is = x – 1
Example.- Predecessor of 77 is = 77 – 1 = 76
Predecessor of 105 is = 105 – 1 = 104
Predecessor of 62 is = 62 – 1 = 61
