how to use braces an ellipsis and digits to illustrate the set of negative odd numbers?

To illustrate the set of negative odd numbers using braces, an ellipsis, and digits, you can write it as: ({ -1, -3, -5, -7, \ldots }). This notation shows that the set includes all negative odd integers starting from -1 and continuing indefinitely in the negative direction. The ellipsis indicates that the pattern continues, encompassing all odd numbers that are less than zero.
