For any series ∑ n = 1 ∞ a n ∑ n = 1 ∞ a n that converges absolutely, the value of ∑ n = 1 ∞ a n ∑ n = 1 ∞ a n is the same for any rearrangement of the terms. A series that converges absolutely does not have this property. In general, any series ∑ n = 1 ∞ a n ∑ n = 1 ∞ a n that converges conditionally can be rearranged so that the new series diverges or converges to a different real number. We point out that the alternating harmonic series can be rearranged to create a series that converges to any real number r r however, the proof of that fact is beyond the scope of this text. In Example 5.22, we show how to rearrange the terms to create a new series that converges to 3 ln ( 2 ) / 2. The terms in the alternating harmonic series can also be rearranged so that the new series converges to a different value. Continuing in this way, we have found a way of rearranging the terms in the alternating harmonic series so that the sequence of partial sums for the rearranged series is unbounded and therefore diverges. Since both of these series converge, we say the series ∑ n = 1 ∞ ( −1 ) n + 1 / n 2 ∑ n = 1 ∞ ( −1 ) n + 1 / n 2 exhibits absolute convergence.ġ + 1 3 + ⋯ + 1 2 k − 1 − 1 2 + 1 2 k + 1 + ⋯ + 1 2 j + 1 > 100. The series whose terms are the absolute values of the terms of this series is the series ∑ n = 1 ∞ 1 / n 2. Since the alternating harmonic series converges, but the harmonic series diverges, we say the alternating harmonic series exhibits conditional convergence.īy comparison, consider the series ∑ n = 1 ∞ ( −1 ) n + 1 / n 2. The series whose terms are the absolute value of these terms is the harmonic series, since ∑ n = 1 ∞ | ( −1 ) n + 1 / n | = ∑ n = 1 ∞ 1 / n. For example, consider the alternating harmonic series ∑ n = 1 ∞ ( −1 ) n + 1 / n. Here we discuss possibilities for the relationship between the convergence of these two series.
