What is the algebraic expression for 3 6 9 12 15?

The sequence 3, 6, 9, 12, 15 can be represented by the algebraic expression (3n), where (n) is a positive integer starting from 1. Specifically, when (n = 1), the expression yields 3; when (n = 2), it yields 6; and so on, producing the sequence. Thus, the expression captures the pattern of increasing multiples of 3.
