Subject: using portions of other methods in a new method

How do you take a piece of a method and use it in another? Here is my
simple example:

class MyArray
  def counter
    result = []
    i = 0
    a = 1
    b = 0
    while i <= 5 do
      a = a + 1
      b = b +1.5
      result << b.to_s + "\t" + a.to_s
      i += 1
    end
    puts result
  end
  def counter2
    counter
  end
end

test = MyArray.new
puts test.counter2

I want counter2 method to take the array "b" and do something with it,
like this:
b.inject {|sum, element| sum+element}
I just can't figure out how to transfer b from one method to another. Is
there a clean way to do this?

Thank you!
