From the above statement the output is 15 and a space


From the right above it should be
X = 6;


In the final screen it should be

15 X = 6


I can't figure out from where the 13 is coming from

Right I just got it the 13 is sent to the screen and X=6 is sent next in the next iteration, with 2 added to 13, that is 15.So finally 13, then in the next iteration 15 X=6 and the final screen looks 13 15 X=6


Am I right?

I see you have worked that out; it might be easier to understand if you count forwards!
