{x|x∈ N and 36$\leq$x$\leq$59 }
{36,37,38,39,… 59} From the given question all the elements are natural numbers and whose values are greater than equal to 36 but less than equal to 59 W is set of elements ‘x’ such that x is a natural number and x is greater than equal to 36 but less than equal to 59 W ={x|x∈ N and 36$\leq$x$\leq$59 }.
