Question
1. Mark each statement True or False. Justify each answer.
(a) If (sn) is a sequence and s; = Sj,
(b) If s, →s, then for every ɛ> 0 there exists Ne N such that n>N implies
|Sn-s|< ɛ.
(c) If sn→ k and t„ → k, then S,= t, for all n e N.
(d) Every convergent sequence is bounded.
then i = j.
2. Mark each statement True or False. Justify each answer.
(a) If sn→0, then for every ɛ> 0 there exists Ne N such that n>N implies
Sn < E.
(b) If for every ɛ > 0 there exists Ne N such that n>N implies s, < E, then
Sn→ 0.
(c) Given sequences (s,) and (a,), if for some s e R, k > 0 and m e N we
have |Sn-s| < kļa, for all n> m, then lim s, =s.
(d) If sns and sn→t, then s t.
= S.
