Astore sells boxes of juice in equal size packs. garth bought 36 boxes, rico bought 18 boxes and mai bought 45 boxes. what is the greatest number of boxes in each pack. how many packs did each person buy if each box contained the greatest number of boxes possible

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
