"Four, four, four, ..." droned the random number generating monster. "Are you sure that's random?" I asked. "That's the problem with randomness, you can never be sure!" he replied. But suddenly the long string of 4s was broken up by an 8, then later a 12, before he returned to his 4s.
Can you complete the following sequence? The answer is not random.
4, 4, 4, 4, 8, 4, 4, 4, 4, 12, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, ?
