ARITHMETIC MEAN BETWEEN (x-y) and (x+y)------------------>

$\frac{x - y + x + y}{2 } \\ \\ \frac{2x}{2} \\ \\ x \: \: \: \: \: \: \: ans.....$

Answer 2

The A.M between (x-y) and (x+y)​ is x.

Explanation:

We know that the arithmetic mean between two numbers a and b is given by :_

$A.M.=\dfrac{a+b}{2}$ , where a and b can be any real number .

[Note : A.M . is the short form to write arithmetic mean]

To find : the A.M between (x-y) and (x+y)​

First number = (x-y)

Second number =  (x+y)​

Therefore , the arithmetic mean between (x-y) and (x+y)​ will be :

$A.M.=\dfrac{ (x-y)+(x+y)}{2}$

$A.M.=\dfrac{ x-y+x+y}{2}$

$A.M.=\dfrac{ x+x}{2}$

$A.M.=\dfrac{ 2x}{2}=x$

Hence, the A.M between (x-y) and (x+y)​ is x.
