Answer 1

Hii friend!!

» If we subtract 1 from any number, we get its PREDECESSOR.
» If we add 1 to any number, we get its SUCCESSOR.

example,
Predecessor of 2 is 1 [2-1]
Successor of 2 is 3 [2+1]

Answer 2

If we can subtract 1 in any number, we get its predecessor.

• A predecessor is a number that comes just before a particular number. For example, if we consider the number 5 and then subtract 1 from 5, we get 4 which is the predecessor of 5.
• However, a successor is just the opposite. The successor of the number 5 will be 6, which can be obtained by adding 1 to 5.
