A what is a list of numbers that often forms a pattern?

A list of numbers that often forms a pattern is called a "sequence." Sequences can follow various rules, such as arithmetic sequences, where each number is obtained by adding a constant, or geometric sequences, where each number is obtained by multiplying by a constant. Examples include the Fibonacci sequence, where each number is the sum of the two preceding ones, and the natural numbers, which follow a simple incremental pattern. These patterns can reveal underlying mathematical principles and relationships.
