Question

Write the predecessor and successor of the given number:

$689990$

Answer 1

A predecessor of any number is the value that comes immediate before the original number.

Therefore, the predecessor of $689990$$=689990-1$

$=689989$

A successor is a term that comes right after a particular number or term or a value.

Therefore. the successor of $689990$$=689990+1$

$=689991$

Hence, the predecessor and successor of $689990$ are $689989$ and $689991$.
