For example, answern2if given the sequence:{1,4,9,16,25,36,...}1.12,14,16,18,...2.316,425,536,649,...2.(1 pt) Find the limit of the sequencean=(cosn)3n.3.(1 pt) Determine whether the sequence is divergent or con-vergent. If it is convergent, evaluate its limit. If it diverges to in-finity, state your answer as ”INF” (without the quotation marks).If it diverges to negative infinity, state your answer as ”MINF”.If it diverges without being infinity or negative infinity, stateyour answer as ”DIV”.limnn2e-4n4.(1 pt) Find the limit of the sequence:an=1n2+7n+4
