WebDec 15, 2014 · 1 Answer Sorted by: 17 The denominator of each term is ( n − 2)! + ( n − 1)! + n! = ( n − 2)! ( 1 + n − 1 + ( n − 1) n) = ( n − 2)! n 2, so each term simplifies to n ( n − 2)! n 2 = 1 ( n − 2)! n = n − 1 n! = 1 ( n − 1)! − 1 n!, and now you can see that the series telescopes.

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).
