overview
The following are explained.
• the number preceding in the order is the predecessor of a given number.
• the number following in the order is the successor of a given number.
The predecessor and successor are explained with the number-line too.
before and after
Whole numbers are ordered in a specific sequence. This is represented by the number line.
Predecessor is the number prior to a number in the order.
Successor is the number that follows a number in the order.
The predecessor of 33 is 22.
The successor of 33 is 44.
The word "predecessor" means: something that comes before or prior in the order.
"pre" means "beforehand" and "decessor" is derived from a word meaning "that departed".
The numbers are ordered 1,2,3,4,⋯1,2,3,4,⋯.
Predecessor of a given number is the number that comes before or prior to the given number.
The predecessor of 33 is 2.
The predecessor of 4 is 3.
The word "successor" means: something that comes after or follows in the order.
The numbers are ordered 1,2,3,4,⋯.
Successor to a given number is the number that follows the given number.
The successor of 3 is 4.
The successor of 4 is 5.
Predecessor: The number that comes before a given number is the predecessor of the given number. The predecessor is one less than the given number.
Successor: The number that comes after a given number is the successor of the given number. The successor is one greater than the given number.
examples
What is the successor of 9?
The answer is '10'. The number-line continues after 9 with 10,11,12,⋯.
What is the predecessor of 13?
The answer is '12'.
What is the predecessor of 233?
The answer is '232'.
What is the successor of 233?
The answer is '234'
What is the predecessor of 1?
The answer is '0'.
summary
Predecessor: The number that comes before a given number is the predecessor of the given number. The predecessor is one less than the given number.
Successor: The number that comes after a given number is the successor of the given number. The successor is one greater than the given number.
Examples:
• predecessor of 3 is 2
• sucessor of 3 is 4
