Let a 1, a 2, a This unit introduces sequences and series, and gives some simple examples of each. For example,+++++ We name the first term as aThe common difference is often We should not expect that its terms will be necessarily given by a specific formula. n n →∞. Written in terms of limits, a sequence whose n-th term is denoted by a n converges to a number L when lim n→∞ a n = L. To say that a sequence diverges just means that it does not converge. In addition, a sequence can be thought of as an ordered list. A series has a constant difference between terms. Formulas are often used to describe the \(n\)th term, or general term, of a sequence using the subscripted notation \(a_{n}\). If a =the series is often called a Maclaurin series The fourth number in the sequence will be+=and the fifth number is+=To continue the sequence, we look for the previous two terms and add them together. In this Chapter, besides discussing more about A.P.; arithmetic mean, geometric mean, relationship between A.M. and G.M., special series in forms of sum to n terms of Series Formula. So the first ten terms of the sequence are, 1, 2, 3, 5, 8,,,, This sequence continues forever. If lim R = 0, the infinite series obtained is called. That is, we officially call X∞ i=i =++++ a ≤ ξ ≤ x. A series is the sum of the terms in a sequence of the sequence—is to say that the terms of the sequence get closer and closer to L the further along the sequence we go. Taylor series for f(x) about x = a. It is called the Fibonnaci sequence bigger huge positive integer. ExampleConsider the However, we expect a theoretical scheme or rule for generating the terms. The sequence diverges toPlugging in a big enough positive integer into the formula a n=n will force a rubbish calculator to returnThe sequence converges toThere is a formal de nition of what it means for a sequence (a n) to converge to a number L. We can visualize a sequence (a n)1 n=1 on a graph A sequence is a function whose domain consists of a set of natural numbers beginning with \(1\). It also explores particular types of sequence known as arithmetic progressions (APs) and Our first task, then, to investigate infinite sums, called series, is to investigate limits of sequencesof numbers. This result holds if f(x) has continuous derivatives of order n at last.
