we know that

If C is between A and B

then

AB=AC+CB

Examples

N

Let

$AB=10\ units \\AC=5\ units$

Find the value of CB

substitute in the equation above

AB=AC+CB

10=5+CB

$CB=5\ units$

in this case

AC=CB

N

Let

$AB=10\ units \\AC=8\ units$

Find the value of CB

substitute in the equation above

AB=AC+CB

10=8+CB

$CB=2\ units$

in this case

$AC\\eq CB$

therefore

the answer is

sometimes
