can someone help me

1) a) For n = 1, 2, 3, ..., define an = 573 + 2 Find a number L such that (an) - L and show from the definition of convergence (i.e., using an NV-e argument) that your answer is correct. b) Let (an) and (bn) be sequences, let L, M E R, and suppose (an ) - L and (bn) - M. Find the limit of the sequence 2an + 3nb, An + 1 Justify your answer, but do not use an Me argument. c) Let a, b E R with a
