SEQUENCE AP AND GP (PART 3)
A sequence is an ordered list of numbers following a specific pattern. An arithmetic progression (AP) is a sequence where each term increases or decreases by a constant difference, given by the formula an = a + (n-1)d, where a is the first term, d is the common difference, and n is the term number. A geometric progression (GP) is a sequence where each term is multiplied by a constant ratio, given by an = a × r^(n-1), where r is the common ratio. AP and GP are widely used in finance, physics, and real-world problem-solving.
