At its core, this is a simple yet powerful mathematical concept defined by a starting value and a steady change. Take this example: a first term of 12, with each next term growing by 3. So the sequence begins: 12, 15, 18, 21, 24—and keeps unfolding in predictable rhythm. Such sequences are far from abstract; they quietly influence how we plan budgets, track progress, and analyze growth across fields like finance, education, and technology.
