Exercise. Select all of the statements that must be true. Note that there may be several statements that are true! Suppose that {an }n21 is a decreasing sequence. Let on = ak and suppose lim sn does not exist. K= 1 lim an does not exist. 00 ak could converge. on MUST diverge. n=1 {on } MUST be monotonic. {on } MUST be bounded. lim Sn = -0o n-too The divergence test applied to > ax would guarantee that > ax diverges. k=1 ?
