What is the sum of the first seven terms of the geometric series 2 − 8 + 32 − . . ? hint: cap s sub n equals start fraction a sub one left parenthesis one minus r to the power of n end power right parenthesis over one minus r end fraction comma r ≠ 1, where a1 is the first term and r is the common ratio. s7 = 6,554 s7 = −8,192 s7 = 8,192 s7 = 10,922

Step-by-step answer

P Answered by PhD

S_7=6554

Step-by-step explanation:

The given series is 2-8+32-...

The first term of the sequence is

a_1=2

There is a common ratio of

r=-4

The sum of the first n terms of a geometric sequence is given by the formula;

$S_n=\frac{a_1(1-r^n)}{1-r}$

We want to find the first seven terms so n=7

We substitute the given values into the formula to obtain;

$S_7=\frac{2(1-(-4)^7)}{1--4}$

$S_7=\frac{2(1--16384)}{1--4}$

$S_7=\frac{2(16385)}{5}$

S_7=2(3277)

S_7=6554

The correct answer is A

How many terms are there in a geometric series if the first term is 2, the common ratio is 4, and the sum of the series is 2,730? hint: cap s sub n equals start fraction a sub one left parenthesis one minus r to the power of n end power right parenthesis over one minus r end fraction comma r ≠ 1, where a1 is the first term and r is the common ratio. n = 3 n = 4 n = 5 n = 6

Step-by-step answer

P Answered by PhD

n = 6

Step-by-step explanation:

Givens

r = 4

a = 2

Sum = 2730

Equation

Sum = a(1 - r^n)/(1 - r)

Solution

2730 = 2 (1 - 4^n) / (1 - 4) Reduce the denominator

2730 = 2(1 - 4^n)/-3 Multiply both sides by -3

2730*-3 = 2(1 - 4^n) Simplify the left

-8190 = 2(1 - 4^n) Divide by 2

-8190/2 = 1 - 4^n Simplify

-4095 = 1 - 4^n Subtract 1 from both sides.

-4096 = - 4^n Divide by - 1

4096 = 4^n This looks like n is fairly large. You could use logs. Try n = 6.

4^6 does equal 4096 So your answer is 6.

Let's try it with logs. Ignore this if you don't know how to do this.

log(4096) = log(4)^n

log(4096) = n*log(4) Divide by log 4

log(4096)/log(4) = n

3.6124 / 0.6021 = n

n = 6
