Question

1. Find arithmetic mean between (a - b) and (a + b)​

Answer 1

Answer:

The ans is a.

Step-by-step explanation:

Arithmetic mean = sum / no. of units

= (a - b + a + b)/2

= 2a/ 2

= a.

Answer 2

Answer:

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}A.M=

2

a+b

.

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=

2

a−b+a+b

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

2

2a

A.M=aA.M=a

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

a.
