Question

Can somebody answer this plz

Answer 1

Answer:

Choice B) {-21, -7, 7, 21}

Step-by-step explanation:

The multiples of 7 are: 0, 7, 14, 21, 28, 35, ... both the positive and negative versions of each number. Erase the even numbers in that list to end up with 7, 21, 35, ...

Choice A fits the description, but there are items missing, namely -7 and 7. So this answer choice is crossed off the list

Choice B has both odd numbers and multiples of 7 listed. Every number is listed. This is why this is the answer.

Choice C has multiples of 7, but these are even numbers. We can cross it off the list.

Choice D is a similar story to choice C, though it has some odd numbers in this list.
