Arithmetic Progression G10

What is common between the three sequences mentioned below 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21; 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66; -27, -24, -21, -18, -15, -12, -9. All of the above sequences are Arithmetic progressions abbreviated as AP. And what do we mean by AP? In an AP, the difference between the two consecutive numbers remains constant throughout the sequence. In this chapter, we will learn about arithmetic and geometric progression in detail.
