Using class knowledge (see ie rental code we wrote create simple class) create a class MyRange that has following methods:

range = MyRange.new(2,6)

range.min #=> 2
range.max #=> 6

range.to_a #=> [2,3,4,5,6]

As a first bonus allow special constructor:

range = MyRange.new(min: 2, max: 6)

This gist will help to understand it: https://gist.github.com/slawosz/8db7fc43e01b9d003564

As a second bonus explore method next:

1.next #=> 2
"A".next #=> "B"

Use this method to be able to create range from any object that supports method next:

range = MyRange.new("A","B")
