You are given eight coins and told that one of them is counterfeit. The counterfeit one is slightly heavier than the other seven. Otherwise, the coins look identical. Using a simple balance scale, how can you determine which coin is counterfeit using the scale only twice?
Answer:
First weigh three coins against three others. If the weights are equal, weigh the remaining two against each other. The heavier one is the counterfeit. If one of the groups of three is heavier, weigh two of those coins against each other. If one is heavier, it’s the counterfeit. If they’re equal weight, the third coin is the counterfeit.

What is the next number in this series?
1, 2, 6, 42, 1806?
Answer:
To get the next number, multiply the previous number in the series by itself plus one: n * (n+1). For example, to get 6, multiply 2 * 2+1. To get 42 multiply 6 * 6+1.
Thus, 1806 * 1807 = 3263442.
