Problem 69E Theory and Examples In the alternating harmonic series, suppose the goal is to arrange the terms to get a new series that converges to –1/2.Start the new arrangement with the first negative term, which is –1/2. Whenever you have a sum that is less than or equal to –1/2, start introducing positive terms, taken in order, until the new total is greater than –1/2.Then add negative terms until the total is less than or equal to –1/2 again. Continue this process until your partial sums have been above the target at least three times and finish at or below it. If sn is the sum of the first n terms of your new series, plot the points (n, sn) to illustrate how the sums are behaving.
