Successor is just opposite of it..

Predecessor of 19 = 18

successor of 19 = 20

Predecessor of 1997 = 1996

successor of 1997 = 1998

Predecessor of 12000 = 11999

successor of 12000 = 12001

Predecessor of 49 = 48

successor of 49 = 50

Predecessor of 100000 = 99999

successor of 100000 = 100001...
