Answer:

r = -3

Step-by-step explanation:

to find r divide the 2nd term by the first:

9/ -3 = -3

to check if this is the same ratio for each number divide it by the ratio to get the number before it:

-27/ -3 = 9

81/ -3 = 27

to find the next three terms multiply the last number by the ratio then repeat

(81)(-3) = -243

(-243)(-3) = 729

(729)(-3) = -2187

Similarity ratio is a ratio of two figures having the same side.

Ratio can be rate but rate can never be ratio. In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.<span>
