Whether an extra variable is better than an extra conditional is mostly a matter of taste. Yours gets the job done too.

Why not just

  if (i % 3 != 0 && i % 5 != 0)

this extra boolean variable out?

I like to think it's matter of readability. "if (pureNumber)" vs. "if (i % 3 != 0 && i % 5 != 0)". Also, one extra variable vs. reversal of already mentioned condition. Yes, we're splitting hair here :)
