Show that N = {1,2,3,...}, E = {2,4,6,...} and Q = {1,3,5,...} are equivalent sets.

 Show that N = {1,2,3,...}, E = {2,4,6,...} and Q = {1,3,5,...} are equivalent sets.

Solution:

 The equivalent sets having the same number of element, therefore in the given sets N,E and Q have the same number of elements.
