The explicit formula for this geometric sequence 81, 27, 9, 3, … is aₙ = 81(1/3)ⁿ⁻¹. It has common ratio of 1/3 and first term of 81.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
A geometric sequence is in the form aₙ = ar⁽ⁿ⁻¹⁾, where a is the first term and r is the common ratio.
The geometric sequence 81, 27, 9, 3, … has common ratio:
r = 27/81 = 1/3

I am not sure about the formula but if you subtract 8,884 from 10,712 you get 1,828. Then, if you divide that by 4 you get 457. 457 fph(feet per hour) should be the climbers vertical speed.
5 cups of chocolate chips to 3 cups sugar
so the ratio of chocolate chips to sugar is : 5/3 or 5:3 or 5 to 3
Answer:
480
Step-by-step explanation:
Find the difference between 2400 and 40 by dividing:
2400 / 40 = 60
Multiply each value by 60:
12 x 60 = 720 chocolate
15 x 60 = 900 caramel
5 x 60 = 300 banana
8 x 60 = 480 marshmallow
