If 2n=1a, converges, and if a„ # 1 and a,n > 0 for all n,
a. Show that E=1a, converges.
b. Does E-1a,n/(1 – a„) converge? Explain.
Determine whether each statement is true or false. If the statement is true, prove it.
If the statement is false, provide a counter-example or other justification.
(a) If {lanl} converges, then {a,} converges.
(b) If {a} converges, then {an} converges.
(c) If {an + bn} converges, then {an} and {bn} both converge.
(d) If {an + bn} and {an} both converge, then {bn} converges.
Do the following:
(a) Give an example of two divergent sequences (an) and (bn) for which (an + bn) converges.
(b) Give an example of two divergent sequences (an) and (bn) for which (an · bn) converges.
(c) Is is possible for a sequence (an) to converge, a sequence (bn) to diverge, and for (an + bn) to
converge? If so, give an example; if not, justify your answer with a proof.
