What is the sum of the first seven terms of the geometric series 2 - 10 +50 -...?

Umnica [9.8K]

Answer:

26042.

Step-by-step explanation:

What's the first term of this geometric series?

What's the common ratio of this geometric series?

Divide one of the terms with the previous term. For example, divide the second term -10 with the first term 2.

$\displaystyle r = \frac{-10}{2} = -5$ .

What's the sum of this series to the seventh term?

The sum of the first n terms of a geometric series is:

$\displaystyle a_1 \cdot \frac{1-r^{n}}{1-r}$ ,

where

$a_1$ is the first term of the series,
$r$ is the common ratio of the series, and
$n$ is the number of terms in this series.

$\displaystyle 2 \times\frac{1- (-5)^{7}}{1- (-5)}=26,042$ .

You pay $30 each month for satellite TV, plus $2.50 for every movie you purchase. Write and solve an equation to find the number

raketka [301]

The initial payment per month being 30 and each movie being 2.50 means that if the total payment is 45 then you pay for 6 movies per month, 30x+6(2.5x)
