Determine the best reason for $ (_1) n2 diverging n=1 3n2 - 1 O an + 1 > an for all n on the interval [1, co) O lim a = 00 1-700 O lim a 1->00 O E (-1)"a converges n=1Given that the series W\" = i (1)"a" converges by the alternating series test, and an is positive and decreasing for all values on the interval [1, 00), which of the following statements best denes n=1 W"? (1 point) 0 W,, is absolutely convergent Wn is conditionally convergent O W" is conditionally and absolutely convergent 0 Not enough information is given about W,, to make a denite statement about convergence
