Question

Find the predecessor of each of the following integers.

$10001$

Answer 1

If $\text{'}a\text{'}$ is any integer, then $\left(a-1\right)$ is known as the predecessor of $\text{'}a\text{'}$.

So, the predecessor of $10001=10001-1\Rightarrow 10000$

Hence, the predecessor of $10001$ is $10000.$
