Write the elements of the set, the odd numbers between, but not including, 799 and 805.

So the keyword here in this question is element because what it means is we want to write the individual parts of our set. And these are known as elements. We can also see the next bit of useful information. And that is that we’re looking at odd numbers. And it must be between, but not including, 799 and 805. So our first value will not be 799; it will be 801 because this is the next odd number. Then, the next odd number that meets our criteria is 803 and then, finally, 805. This will also not be included because we’re told in the question that 799 and 805 are not included. So therefore, the elements of the set, the odd numbers between, but not including, 799 and 805 are 801 and 803. There are two elements.
