Use set notation and write the elements belonging to the set 
{x | x is a natural number less than 6}.

Accepted Answer

Welcome back. I am so glad you're here. We are given a description of a set and we are to express it in set notation. So we're told the set of all elements X. Such that X. Is an integer greater than 137 and less than 141. Okay, so it's going to be greater than 137. It's going to come after that And it's going to be less than 141. So it will end before that. And it has to be all of the integers, integers. Those are the counting numbers we recall from previous lessons. So what are all of those integers in between? I might not have given myself enough space. Let's scoot this over. Just a tap. Okay, so the integer right after 137 is 138. The next integer is 139 and the next integer is 140 yes. The next integer after 1 40 is 1 41. So the set that has been described is 38 1 39 and 1 40. It does not include 1 37 or 1 41 because it says greater than 1 37 and less than 1 41. Alright. We look at our answer choices and this matches with answer choice. C. Well done. We'll catch you on the next one
