Write a multiplication equation and a division equation that this diagram could represent. A tape diagram of three equal parts. Each part is labeled "eighteen". A brace from the beginning of the diagram to the end of the disgram is labeled "54".

Group of answer choices

3 • 18 = 54 and 54 ÷ 18 = 3

54 • 3 = 18 and 18 ÷ 3 = 54

c

3 • 18 = 54 and 54 ÷ 18 = 3

3 • 18 = 54 and 18 ÷ 54 = 3

The model of this scenario is:

This gives:

-- This represents the multiplication model

Divide both sides by 18

Reorder

-- This represents the division model

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
