The sequence "2, 5, 8, 11" is an example of an arithmetic progression, where each number increases by a constant value. In this case, the difference between each number is 3. This pattern continues indefinitely, meaning you can keep adding 3 to get the next number, like 14 or 17. Arithmetic progressions are useful in various fields, including mathematics and finance. They help in calculating things like interest rates or predicting future values. Understanding this sequence can also enhance problem-solving skills, making it easier to tackle more complex mathematical concepts in the future.
