This can return: num1 = 1000, num2 = 1001, number = 2001

Try

module RandomNumberBetweenTwoRandomNumbers
    def self.generate max
        first = 1 + rand(max - 2);
        second = max - rand(max - (first + 1))
        between = first + 1 + rand((second - first) - 1)
        [first, between, second]
    end
end

puts RandomNumberBetweenTwoRandomNumbers::generate 10
puts RandomNumberBetweenTwoRandomNumbers::generate 100
puts RandomNumberBetweenTwoRandomNumbers::generate 1000
