Could someone please help me with this question

For each sequence, find the set S of subsequential limits, the limit superior, and the limit inferior. 1. Let Sn = (- 1)". o The limit superior of Sn is: O -1 1 e 0 DNE O O o The limit inferior of Sn is: -1 1 e . DNE O O o Explain: 2. Let (tn) = 1 11 1 2'1, 4'3' 6'5'.). o The limit superior of tn is: DNE 0 1 /2 1 e co O O o The limit inferior of tn is: DNE 0 1/2 1 e co O O o Explain
