Question

How do i write d={2,4,6,8,10,12,14} in set builder notation?

Answer 1

There are many ways

d = {x | x is an even number with 0<x<16}

is one.

Answer 2

This can be written as d={x : x=2n, where 1<_n<_7, and n is a whole number}

Another way could be d={x : x is a positive even integer and 2<_x<_14}
