Answer 1

Question -

The arithmetic mean of 15 and 17 is ____________

Solution -

We know that for two numbers , a and b in Arithmetic Progression ,

Arithmetic Mean = [ a + b ] / 2

Here,

Substituting the required values -

Arithmetic Mean = [ 15 + 17 ] / 2

=> [ 32/ 2 ]

=> 16

Hence the arithmetic mean if the two numbers is 16 .

So, the answer becomes -

Answer -

The arithmetic mean of 15 and 17 is 16 .

Additional Information -

• Geometric Mean -

For two numbers, a and b in Geometric Progression ,

Geometric Mean = √{ ab}

• Harmonic Mean -

For two numbers, a and b in Harmonic Progression ,

Harmonic Mean = [ 2ab / a + b ]
