You can get a predecessor by subtracting 1 from the given number.Examples : a. 4287 : 4287 %u2013 1 = 4286 Predecessor of 4287 is 4286.b. 3820 : 3820 %u2013 1 = 3819 Predecessor of 3820 is 3819.c. 9999 : 9999 %u2013 1 = 9998 Predecessor of 9999 is 9998.The number that comes just after a given number is called the successor. You can get a successor by adding 1 to the given number.Examples : a. 4928 : 4928 + 1 = 4929 Successor of 4928 is 4929.b. 3808 : 3808 + 1 = 3809 Successor of 3808 is 3809.c. 1999 : 1999 + 1 = 2000 Successor of 1999 is 2000.I.
