235D00.1666666666666672.(1 point) Find the sum of the following infinite series. If itis divergent, type ”Diverges” or ”D”.11+2+411+8121+···Sum:Answer(s) submitted:121/9(correct)3.(1 point) The following series are geometric series or a
sum of two geometric series.Determine whether each series converges or not.For the series which converge, enter the sum of the series. Forthe series which diverges enter ”DIV” (without quotes).
DIV10.3754.(1 point) Letr=1823.For both of the following answer blanks, decide whether thegiven sequence or series is convergent or divergent. If conver-gent, enter the limit (for a sequence) or the sum (for a series). Ifdivergent, enter INF if it diverges to infinity, MINF if it divergesto minus infinity, or DIV otherwise.A. Consider the sequence{nrn}.limnnrn=0414/25(correct)B. Take my word for it that it can be shown thatni=1iri=nrn+2-(n+1)rn+1+r(1-r)2.Now consider the seriesn=1nrn.n=1nrn=Answer(s) submitted:
