Question

two arithmetic mean between 5 and 11 are


​

Answer 1

Answer:

Given:

a=5,b=11 and n=2

The common difference for inserting arithmetic means are calculated as d=11-5/2+1=2

d=2

Using the above value of d, the two arithmetic means will be,

A1=5+2=7

A2=5+2(2) =9

So, the two numbers are 7 and 9.

Answer 2

Given: $a=5, b=11, n=2$

We have to find the two arithmetic mean between 5 and 11.

The common difference is

$d=11-\frac{5}{2} +1$

$d=2$

Arithmetic mean will be,

$a1=5+2\\=7\\\\a2=5+2*2\\=5+4\\=9$

Two numbers are 7 and 9.
