During an outbreak of the flu, a hospital recorded 24 cases the first week, 84 cases the second week, and 294 cases the third week. Which recursive formula can you use to determine the number of flu cases recorded in the nth week?

Answer 1

take the # in the last week and times it by 3.5 than you should get the next week. ex: if you wanted to find the 9th week you could do 84 times 3.5 8 times
