A pack of bottled water cost 2.40 and eight pack of bottled water cost 3.20 which is the better deal

eight pack of bottled water is the better deal

Step-by-step explanation:

Cost of eight pack of bottled water = 3.20

Cost of one pack of bottled water = 3.20/8 = 0.40

So, eight pack of bottled water is the better deal

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
