Predecessor : As we know that predecessor means before number. There are two methods to find the before number.
1) Say the counting numbers and stop at the number up to which you have to find the before number.
Example : Find the before number of 9 .
Say 1,2,3,4,5,6,7,8,9 so before 9 we said 8 so 8 is the predecessor of 9.


Note : There is no predecessor of whole number zero. 

Successor There are two methods to find the successor of the given number.
1) Say the counting numbers and stop at the given number and say the next number that will be the successor of the given number.
Example : Find the successor of 12 . 
Say 1,2,3,4,5,6,7,8,9,10,11,12 and then the next number is 13 so 13 is the successor of 12.
