Write the successor and predecessor of the following numbers.

$10,25,731$

Answer 1

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

So, the successor of $10,25,731=10,25,731+1$

$=10,25,732$

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

So, the predecessor of $10,25,731=10,25,731-1$

$=10,25,730$

Hence, the successor and the predecessor of $1,25,731are1,25,732and1,25,730$respectively.
