Solve 2.34 in detail please 

i have posted this earlier too so please don't copy that wrong answer 

Example 2.17. On N, let {{0, 1}, {2, 3}, {4, 5},.} be a subset of a topology Tad- What other sets must be in Tad at a minimum for it to be a topology on N? ....

Problem 2.32. Is there an example of a space X, a subset Y C X, and a point x E X such that x is a limit point of Y, but not a sequential limit point of Y? 2.4. Subspace Topology. Sometimes we use a given topology on a set X to induce con- veniently a topology on a subset of X. Definition 2.33. Let X be a space with topology T and Y c X. T induces a topology Ty on Y, called the subspace topology on Y, given by Ty := {V cY | BU € T,V = U nY}. Problem 2.34. Let E CN be the set of even natural numbers. Give N the topology Tad (see Example 2.17). Describe the subspace topology on E. Exercise 2.35. Let X be a space, Y C X, and ZC Y. Give Y the subspace topology. Then the subspace topology on Z as a subspace of X is the same as the subspace topology on Z as a subspace of Y.
