Limits of sequences Write the first four terms of each sequence. If youbelieve the sequence converges, make a conjecture about its limit. If the sequence appears to diverge, explain why.a. { (-1)n/(n2 + 1)}∞n = 1                                        Explicit formulab. {cos nπ}∞n = 1                                                     Explicit formulac. {an}∞n = 1, where an + 1 = -2an, a1 = 1      Recurrence relation
