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 ...

The sequence shows how simple rules can create complex but predictable patterns. Tip Every third number in the sequence is even, and the sum of any 10 consecutive Fibonacci numbers is divisible by 11.

These sequences belong to combinatorics, a branch of mathematics that deals with number patterns in sets of elements. The most famous combinatorics sequence, called the Catalan numbers, ...

The sequence starts with 1, so the next line is “one 1” (aka 11), the following line is “two 1’s” (aka 21), then you get “one 2, one 1” (aka 1211), and so on. The pattern can never ...

Professor Ken Ono from the University of Virginia has made a discovery that could redefine the mathematical understanding of ...

1, 1, 2, 3, 5, 8, 13, 21, 34... why is this pattern seemingly everywhere? In terms of math, the sequence isn't too hard to get your head around. In short, each number is the sum of the two numbers ...
