Answer 2

Answer:

Step-by-step explanation:

successor: 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. Clearly, the successor of 0 is 1; successor of 1 is 2; successor of 2 is 3 and so on.

predecessor: 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. Clearly, the predecessor of 1 is 0; predecessor of 2 is 1; predecessor of 3 is 2 and so on. The whole number 0 does not have any predecessor. We observe that every whole number, other than zero, has its predecessor. Also, if a is the successor of b, then b is the predecessor of a.
