(e) lim cr=0 but c.diverges. What is a c, that makes this statement true? 0p
Is the below statement True or False? If lim an=0 then a, must be convergent. n=0
Determine whether each of the following is Always True,
Sometimes True, or Always False. If the statement is Always True or
Always False, provide a brief justification. If the statement is
Sometimes True, provide an example of a series that makes it true
and an example of a series that makes it false. In the following,
{a_n}∞n=1 is a sequence and {s_n}∞n=1 refers to the corresponding
sequence of partial sums.
(a) If lim n→∞ s_n = 0, then lim n→∞...

(4 pts) Choose the true statement. Let a,b,c e Z with a #0. If a|(b + c) and a|bc, then a|(+ c´). Let a,b,c e Z with a +0. If a|(62 +c), then a|(b+c). Let a, b, ce Z with a + 0. If a|(b+c), then aſb or a|c. Let a,b,c e Z with a +0. If a|(62 +c) and a|(b+c?), then a|(+ c´). the four other possible answers are false

In each of the following, fill in the corresponding box by: • Expressing the limit in terms of A, B, C if it is possible to do so using the given information; • Writing DNE if it is possible to conclude that the limit does not exist using the given information; • Putting a X. otherwise.
