Question

Insert single arithmetic mean between 8 and 26​

Answer 1

Answer:

17

Step-by-step explanation:

Single AM between 2 No.s a & b is given by

(a+b)/2

Single AM between 8 & 26

= (8+26)/2 = 34/2 = 17

Answer 2

17

It is the simple average or sum of a series of integers divided by the total count of those numbers.

A represents the arithmetic mean of numbers 'a' and 'b'.

As they are in A.P.,

the difference between those will be constant

   A - a = d and

   b - A = d

Therefore, A - a = b - A

            2A = a + b

                         A = $\frac{a+b}{2}$  

Thus the required arithmetic mean (A.M) of two numbers 'a' and 'b' is  

$\frac{a+b}{2}$

       Given that, a= 8

                          b= 26

Arithmetic mean=

                           = $\frac{34}{2}$

                           = 17

Single arithmetic mean between 8 and 26 is 17.
