The Mystery: 4, 8, 15, 16, 23, 42 (and their sum 108) run through all of Lost; theyre the corresponding numbers on Jacobs list of the final six candidates, the variables on the Valenzetti equation, the numbers Hurley won the lottery with, the sequence that must be put into the Swan computer and so many more background appearances even Lostpedia can't fit them all in one page. Despite being such an integral part of the show, the numbers were made up halfway through Season 1, so clearly weren't part of the original plan. Still, given how the show would continuously adapt itself, everyone expected there to be some overarching solution. The Simple Solution: They were just numbers. Do you think we crashed on this place by coincidence? Locke asks Jack in the Season 1 finale. While he may have been right to question that in relation to the passengers of Oceanic 815 being brought to the Island, as far as the numbers are concerned that is exactly what it was. Many of their appearances were linked (their obsession with the Valenzetti equation probably inspired Dharma to use them for the Swan's computer sequence, as well as transmitting them from the island, which in the end led to Hurley playing the lottery with them, while his recurring bad luck was Jacob pushing him towards the Island), but theres no underlying force to it. The show just put too much emphasis on them, leading to the illusion of importance. Got any more Lost mysteries people always think are unanswered, but actually are?
