Write any three rational numbers between `-2\ a n d\ 0.`

Explanation

There are infinite rational numbers between two rational numbers.

if a and b are the two rational numbers then rational numbers between them can be `(a+b)/2, (a+(a+b)/2)/2, (b+(a+b)/2)/2`.

here a=`-2 and b=0`

the three rational numbers are - `-1,-1.5,-0.5`
