How to solve telescoping series
WebDec 28, 2024 · We again have a telescoping series. In each partial sum, most of the terms cancel and we obtain the formula Sn = 1 + 1 2 − 1 n + 1 − 1 n + 2. Taking limits allows us to determine the convergence of the series: lim n → ∞Sn = lim n → ∞(1 + 1 2 − 1 n + 1 − 1 n + 2) = 3 2, so ∞ ∑ n = 1 1 n2 + 2n = 3 2. This is illustrated in Figure 8.11 (a).

WebTelescoping series is a series where all terms cancel out except for the first and last one. This makes such series easy to analyze. In this video, we use partial fraction decomposition to find sum of telescoping series. Created … WebThis test is used to determine if a series is converging. A series is the sum of the terms of a sequence (or perhaps more appropriately the limit of the partial sums). This test is not applicable to a sequence. Also, to use this test, the terms of the underlying sequence need to be alternating (moving from positive to negative to positive and ...
