For each real-valued sequence, explain whether limn→∞ Sn is convergent, divergent to to, or otherwise divergent (not to ±∞). If it is convergent, find its limit. If it is divergent, find its lim sup and lim inf. (a) Sn = (b) Sn = n− (−1)n.n² 10n +1 2n - (-1)".n 10n1 (c) so = 5, Sn+1 = √Sn +2 for n ≥ 1 (recursively defined).
