Acompany is making detergent out of soap and water. they made one batch that has 30% soap and another batch which is 60% soap. if they mix 600 liters of the first batch with 300 liters of the second batch, what percent of soap will be in the detergent?

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
