School quizzes occasionally contain a puzzle so fiendish that it even stumps intelligent adults. (Teachers have to get their kicks somehow, y’know.) The above brain-teaser recently appeared on an elementary school entrance exam in Hong Kong and quickly went viral. How long will it take you to solve it?
Study the above puzzle. You need to work out what number is obscured by the car based on the visible sequence of numbers — 16, 06, 68, 88, [blank] and 98.
If you know the trick to this puzzle, it should only take a few seconds to work out. For everyone else, try not to get too caught up in complex sequencing — it’s a lot easier than you think. We like this puzzle because it forces you to apply logic and think outside the box: the only barrier to the solution is your own thought process.
If you don’t work it out immediately, don’t feel too bad — apparently, many adults have a hard time with it, whereas kids are quicker to find the answer. (We’ll leave it to one of our readers to provide the solution in the comments!)
