34, which of the following is/are true for the set a ,nen, n23 (a) sup a = 1 (b) inf a = 1 (c) sup a 3 d) inf a =

by monotone convergence theorem, as it is monotonic increasing seq and convergent so must converge to its superimum.

This is a monotonic increasing sequence. Hence its sup value is 1 and inf. value is 3rd root of 1/3. option a and d are correct . Check attachment.
