What does the alternating series test O Nothing, this is not an alternating series and therefore say about ) (-1)"+17 the alternating series test does not apply. n=1 The series diverges because the an are not all positive. The series diverges because lim an is not 0. The series converges. 22) Does the following infinite series O It converges. converge or diverge? O It diverges. 1 O It cannot be determined. mi n2" 23 What is the sum of O O O 24 What does the alternating series test O Nothing; this is not an alternating series and, therefore, say about (-1)"+1 the alternating series test does not apply. The series diverges because the an are man(n+1) not decreasing. The series diverges because lim an is not 0. O The series converges
