The sequence "2، 4، 6، 8" represents a simple pattern of even numbers. Each number is an integer that can be divided by 2 without leaving a remainder. This sequence starts at 2 and increases by 2 with each subsequent number, making it a basic example of arithmetic progression. Even numbers, like those in this sequence, are important in mathematics and everyday life. They are often used in counting, grouping, and various calculations. The concept of even numbers is foundational in number theory and is applicable in various fields, including computer science and engineering.
