Margot is looking at some information for the obstacle course she is interested in completing The x-coordinate is the number of the obstacle, while the y-coordinate

is the average time to complete the obstacle, measured in minutes

(1.6 25), (2.6875), (3, 7.5625), (4,8,31875)

Help Margot use an explicit formula to find the average time she will need for the 8th obstacle.

(8) 11(6.25): (8) 409782

(8) = 6.25(1.1) (8) = 12.179

(8) = 11(625) (8) = 2561137

(8) = 6.25(1.1) (8) 13.397

The average time that Margot will need for the 8th obstacle is f(8) = 6.25(1.1)7; f(8) = 12.179.

What is the average time about?

Not that the values are:

(1, 6.25), (2, 6.875), (3, 7.5625), (4, 8.31875)

Where r= 1.1  

And f(1) = 6.25  and thus this act as the starting or beginning number.

Because we have to multiply each number by 1.1, therefore, we use Geometric Explicit Formula which is:

f(n)= f(1) x r ^n-1

f(8) = 6.25 x 1.1 ^(8-1)

f(8) = 6.25 x 1.1 ^7

f(8) = 6.25 x 1.9487171

Therefore, f(8) = 12.179

So we can say that the average time that Margot will need for the 8th obstacle is f(8) = 6.25(1.1)7; f(8) = 12.179.
