Answer 5

so it's asking for the fifth number in the sequence. you already know the first three (600, 300, 150) and you know that each of those numbers is getting smaller by dividing by two. so to find the fourth number in the sequence you would divide the third number by 2 so you get 75. then the fifth number would be 75 / 2, hence my answer
