Detailed Solution

To find the number of rational numbers between two rational numbers.
Consider

a and b

as rational numbers. Then a rational number

n_{1}

can be find in between

a and b

such that

a < n_{1} < b

using the formula

n_{1} = \frac{a + b}{2}

.
Similarly, again we can find a rational number between

a and n_{1}

and

n_{1} and b

and so on.
Hence, between any two distinct rational numbers there are infinitely many rational numbers.
Therefore, option 3 is correct.
