Question

Write the successor and the predecessor of the following numbers.

$4$

Answer 1

Predecessor: The predecessor of a natural number is one less than the given number.

So, the predecessor of $4$ is $=4-1=3$

Successor: The successor of a natural number is one greater than the given number.

So, the successor of $4$is$=4+1=5$

Hence, the successor and the predecessor of $4$ are $5\text{and}3$respectively.
