Suppose U= {…,-5,-3,-1,1,3,5,…} is the universal set and R= {1,3,5,…}. What is R’
R' is the complement of set R within the universal set U. It includes all the elements of U that are not in R.
Since R contains all the odd positive integers, R' would include all the even positive integers, as well as the negative numbers.
Therefore, R' can be written as R' = {…, -6, -4, -2, 0, 2, 4, 6, …}
