Find the sum of the first 8 terms of the following series, to the nearest integer. 36, 30, 25, ...

The sum of the first 8 terms will be:

Step-by-step explanation:

Given the sequence

A geometric sequence has a constant ratio and is defined by

computing the common ratio

As the first element is

so the nth term will be:

Geometric sequence sum formula

Plugin the values to determine the sum of the first 8 terms

 Therefore, the sum of the first 8 terms will be:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

i think it would be 42cm
