The following is the ingredients to make 2 loaves of bread How much flour is needed to make 3 loaves of bread?

3 3/4 or 3.75

Step-by-step explanation:

i divided 2 1/2 and got 1 1/4 or 1.25 which is how much you need for 1 loaf. Then I added the original 2 1/2 or 2.5 back to it to get 3.75 or 3 3/4.

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
