Question

difference of any number and its successor is

Answer 1

successor is the one no. greater than the given no. for example 24 so the successor of 24 is 25

Answer 2

$\textbf{Answer}$

$\textbf{What is successor of a number ?}$

$\textbf{Successor}$ of a given number is the number obtained by adding 1 to the given number.
$\textbf{For example,}$ lets suppose any number 10,
So the successor of 10 = 10+1 = 11.
So the difference between 10 and 11 = 11-10 = 11

$\textbf{What is predecessor of a number ?}$
$\textbf{Predecessor}$ of a given number is the number obtained by subtracting 1 from the given number.

$\textbf{Lets get back to the question,}$
We need to find the difference of any number and its successor.

Since successor of any number is the the number that is 1 larger than the given number,
So the $\textbf{difference}$ between $\textbf{any number and its successor}$ is $\textbf{always 1.}$
