The sequence "0, 1, 2, 4" represents a simple numerical pattern. It starts with 0, which signifies the absence of quantity. The next number, 1, is the first positive integer, representing a single unit. Following that, 2 indicates two units, and 4 shows four units, which is double the previous number. This sequence can be observed in various contexts, such as in mathematics and computer science. For example, binary code uses 0 and 1 to represent data, while set theory often starts with 0 as the cardinality of an empty set.
