Question

If a sequence <S> is convergent, then it is
(a) a Cauchy sequence
(b)not a Cauchy sequence
(c) may or may not be a Cauchy sequence
(d) none of these​

Answer 1

Answer:

So, for any index n and distance d, there exists an index m big enough such that am – an > d. (Actually, any m > (√n + d)2 suffices.) As a result, despite how far one goes, the remaining terms of the sequence never get close to each other, hence the sequence is not Cauchy.
