How to get back to the beginning of a loop when the loop ends

Okay my question might sound confusing, but here's what I'm trying to do.

I'm supposed to do some calculation within a loop, and then, at the end of that loop, I use whatever I get out to plug back into the beginning of the loop and basically start that same loop again. For example,

n = 1;

for n < 20

    a = 20 + r
    V = a + 4
    if V < 20
        some calculation
        V = 4 * x + y
        ...
    end
    n = n + 1;
end

So, at the end, I get V equal to something.

Then I want to use this new value of V that I just got and put it back into the above loop to evaluate if this new V is less than 20. If it is, then perform everything in that loop again.

How do I do this?

Thank you so much!

Use a while loop:

r = 0.1; n = 1;

while n < 20

      a = 20 + r
      V = a + 4
      if V < 20
          some calculation
          V = 4 * x + y
          ...
      end
      n = n + 1;
  end

The 'r' in my question is just some input that the user has to enter.

So, how would you form that while loop exactly? I already have a while loop going on.

Thank you

Just the way I listed here. You can nest while and other types of loops.

I needed a value for r to test the code.
