![]() Here every number is just half of the previous one. The rule here is: keep adding +1 to the preceding number until you reach 2, then put a pause. Other examples of convergent sequences include: Looking at this sequence, you are most likely to surmise that the numbers always come closer to 100, and you’d be right. In the world of trade and finance, convergence and divergence are terms used to define the directional association of two prices, trends or indicators.Ī convergent sequence, a sequence of numbers in which numbers come ever near from a real number (known as the limit):įor example, 70, 80, 90, 95, 97, 98, 99, 99.5, 99.8, 99.9, 99.999…. ![]() ![]() The interval −1 < x < 1 is known as the range of convergence of the series for values of x on the exterior of this range, the series is declared to diverge.ĭifference Between Convergent and Divergent MathĬonvergence usually means coming together, whereas divergence usually implies moving apart. In the same manner as the above example, for any value of x between (but exclusive of) +1 and -1, the series 1 + x + x 2 + ⋯ + x n converges towards the limit 1/(1 − x) as n, the number of terms, increases. The line y = 0 (the x-axis) is known as an asymptote of the function. Even so, no finite value of x will influence the value of y to really become zero, the limiting value of y is zero (0) since y can be made as small as wanted by selecting 'x' huge enough. For instance, the function y = 1/x converges to zero (0) as it increases the 'x'. Convergent definition in mathematics is a property (displayed by certain innumerable series and functions) of approaching a limit more and more explicitly as an argument ( variable) of the function increases or decreases or as the number of terms of the series gets increased.
