Question

Write the predecessor of each of the following numbers:

$7620\_\_\_\_\_\_\_\_\_\_\_$

Answer 1

A predecessor is a value that comes right before/immediate before/just before a particular value. Suppose a value is $n$ (where $n$ belongs to any whole number), then the predecessor of $n$ will be $1$. Thus, to find the predecessor of any value we have to subtract the given value from $1$.

Hence, predecessor of $7620$ is $7620-1=7619$.
