This sounds like a homework problem to me, maybe you should to a little more studying. Why else would you include the "answer."

This is an example of the kind of question that might appear in the final exam and although I have done 4 weeks of PHP, I dun quite get the reason for the output, which was given by my prof...

You've spent more time on daniweb than hitting your books. Not a bad thing to do, but you need to do your own work now.

Clue: what type of numbers does $i % 2 == 1 give you??

I guess, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, etc...
Am I correct?

X = 2 rite,
Then howcome the answer to the code is:
1 x 3, 2 x6, 3 x 12, 4 x16, 5 x 25, 6 x30

x++(shouldn't it be 3, 5, 7, 9, 11, 13)

I am confused...

Paid รข bod yn wirion, gwranda, rwyt wedi derbyn sawl darn o god yn rhad ac am ddim, cer i wneud gwaith dy hun.

In a word, no.

I think your semester average has been bumped enough already. You get the grades you deserve at the end.

False dawns and dead ends are the making of men. What feeble excuse of a man shall you turn out to be if you continue to complete a crossword by first checking the answers?

Go forth and pound thy books.
Happy Humbugging Christmas
