# Successor and Predecessor of the Whole Number:

• The number which comes immediately after a particular number is called its successor. The successor of a whole number is the number obtained by adding 1 to it. For example, the successor of 2 is 3.

• The number which comes just before a particular number is called its predecessor. The predecessor of a whole number is one less than the given number. For example, the successor of 9 is 8.

• Successor and predecessor apply only to whole numbers. This means that they apply to numbers like zero, one, two, three, and so on which means they also don’t apply to decimals, fractions, or negative numbers. There is no predecessor of whole number zero. Every natural number has a successor. Every natural number except 1 has a predecessor. Every whole number has a successor. Every whole number except zero has a predecessor.
