What am I doing wrong here.

I don't know where did I do wrong.

Please advise.

(1 point) We will deten'nlne whether 'the series l5" 2r1"=21":'ls Is convergent or divergent using the comparison test. Note that the ashes has positive terms, which Is a requirement for applying the comparison test. First we must find an appropriate series 2 bn for comparison {this series must also have positive terms}. The most reasonable choice is b" = [inn (eliminate everything but the fastest- growing parts ofths numerator and denominator). Which of the following is true? ("whoa {bnforallnzl 03.0,, 1':- b" foralln 3] (:3 6. none of the above The series E [1,, is a divergent series with ratio r = 6 and hence it is divergent (enter "converrc'pent'I or "divergent"]. Finally, by the Comparison Testvve conclude that the series I: an is divergent [enter "convergent\" or \"d ivergent")
