What is the order of the set a={-1,20,3,17,5}
To find the order of a set, you need to arrange the elements in the set in either ascending or descending order. In this case, the set is a = {-1, 20, 3, 17, 5}.
To arrange the elements in ascending order, start with the smallest element and continue in increasing order.
The smallest element in the set is -1. Next, we have 3, 5, 17, and finally 20.
Therefore, the set a arranged in ascending order is a = {-1, 3, 5, 17, 20}.
The order of the set a is {-1, 3, 5, 17, 20}.
