Question

How to find three rational number between two numbers?

Answer 1

Step 1: Find the common difference

Let the first number be $a$ and the second number is $b$.

We have to find three rational number between $a$ and $b$.

Let $d$ be the common difference .

Then the common difference should be $d<\frac{b-a}{3}$

Step 2: Find the rational number between two numbers

Then the three rational number between $a$ and $b$ are

$a+d,a+2d,a+3d$

Hence, the three rational number between $a$ and $b$ are $a+d,a+2d$and $a+3d$.
