A pattern or a sequence is a set of numbers that are connected in some way. All sequences have a rule. For example, sometimes the numbers might count on by 5 each time, other times they might be ...

Some strange mathematical sequences are always whole numbers — until they’re not. The puzzling patterns have revealed ties to graph theory and prime numbers, awing mathematicians. Simple, yes, but ...

One of the curious properties of mathematics is its beauty. But exactly what mathematicians mean by beauty is hard to capture. Perhaps the most famous example is Euler’s relation, e iπ + 1 = 0, which ...

For more than 50 years, the mathematician Neil Sloane has curated the authoritative collection of interesting and important integer sequences. Neil Sloane is considered by some to be one of the most ...
