am = a

Answer 2

The arithmetic mean between (a-b) and (a +b) is a.

Step-by-step explanation:

To find : The arithmetic mean between (a-b) and (a +b)?

Solution :

The arithmetic mean between a and b is $A.M=\frac{a+b}{2}$.

The arithmetic mean between (a-b) and (a+b) is given by,

Here, a=(a-b) and b=(a+b)

Substitute in the formula,

$A.M=\frac{a-b+a+b}{2}$

$A.M=\frac{2a}{2}$

$A.M=a$

Therefore, the arithmetic mean between (a-b) and (a +b) is a.
