Question

difference between predecessor and successor of a no is???

Answer 1

a predecessor is someone who has had a particular job or position before. Dictionary.com defines 'Successor' as, “a person or thing that succeeds or follows” and “a person who succeeds another in anoffice, position, or the like”. Successor is also a number that follows or just comes after a particular number.

Answer 2

predecessor = before number.
successor = after number.
