Find the sum, thank you

Consider the following series. 9 +en 1 = What does the Test for Divergence reveal about this series? O Converges; the limit of the terms a is a constant as n goes to co. O Converges; the series is a constant multiple of a geometric series. Diverges; the series is a constant multiple of the harmonic series. Diverges; the limit of the terms a is not 0 as n goes to co. O Diverges; the sequence a diverges as n goes to co. If it is convergent, find its sum. (If the quantity diverges, enter DIVERGES
