Question

Proving the Alternating Series Test (Theorem 2.7.7) amounts
to showing that the sequence of partial sums

                sn = a1 − a2 + a3 −· · ·±an

converges. (The opening example in Section 2.1 includes a typical illustration of (sn).) Different characterizations of completeness lead to different proofs.

(a) Prove the Alternating Series Test by showing that (sn) is a Cauchy
sequence.

(b) Supply another proof for this result using the Nested Interval Property
(Theorem 1.4.1).

(c) Consider the subsequences (s2n) and (s2n+1), and show how the Monotone Convergence Theorem leads to a third proof for the Alternating Series Test.
