determine if the sequence is geometric if it is find the common ratio the 8th term and the explicit formula can someone check my

mylen [45]

Answer:

You can check the answer by yourself after seeing the below answer.

Step-by-step explanation:

A sequence is geometric only if has common ratio i.e. $r=\frac{a2}{a1} =\frac{a3}{a2}$ whiere a1,a2 and a3 are first,second and third term of the sequence respectively.

1) Common ratio $r=\frac{-18}{-3}=\frac{-108}{-18}=6\\$

Explicit formula $a_{n} =a_{1} .r^{n-1}$

Now using the above formula, we can find $8^{th} term=-3*(6)^{8-1} =-3*6^{7}=-839808.$

2) Here

$\frac{a2}{a1}\neq \frac{a3}{a2}\\\frac{-2}{-4}\neq \frac{1}{-2}\\\frac{1}{2}\neq\frac{1}{-2}$ so this is not geometric sequence so no need to proceed further.

3) Common ratio $r=\frac{15}{-3}=\frac{-75}{15}=-5\\$

Explicit formula $a_{n} =a_{1} .(-5)^{n-1}$

Now using the above formula, we can find $8^{th} term=-3*(-5)^{8-1} =-3*(-5)^{7}=234375.$

4) Common ratio $r=\frac{-6}{1}=\frac{36}{-6}=-6\\$

Explicit formula $a_{n} =a_{1} .(-6)^{n-1}$

Now using the above formula, we can find $8^{th} term=1*(-6)^{8-1} =1*(-6)^{7}=-279936.$

5)Common ratio $r=\frac{-8}{4}=\frac{16}{-8}=-2\\$

Explicit formula $a_{n} =a_{1} .(-2)^{n-1}$

Now using the above formula, we can find $8^{th} term=4*(-2)^{8-1} =4*(-2)^{7}=-512.$

6)Common ratio $r=\frac{-8}{-2}=\frac{-32}{-8}=4\\$

Explicit formula $a_{n} =a_{1} .(4)^{n-1}$

Now using the above formula, we can find $8^{th} term=-2*(4)^{8-1} =-2*(4)^{7}=-32768.$

xenn [34]

Answer: I believe the answer is C.

Step-by-step explanation: In special case isosceles right triangles the hypotenuse is always equal to a · √2. With a=5√2 we can set up the equation 5√2 · √2 = 10.

A study was made to find out if those who drank tea consumed more water than those who did not. The study concluded that those w

kirill [66]

I would say that the results of the study are not significant. This is because the difference of those who drink tea and did not drink tea is small and more or less will have the same values at some points of the research. Having a difference of 0.024, cannot really say anything or differentiate the two.

6/8 is equivalent to 3/4. How can you use this to help you write 6/8 as a decimal?

Alexus [3.1K]

Answer:

0.75 is the answer

Step-by-step explanation:

6/8 is equivalent to 3/4

3 divided by 4 is 0.75

Since 6/8 is equivalent then it is also 0.75

Also 6/8 turn to 3/4 when both the numerator and denominator is divided by 2.

6 divided by 2 is 3

8 divided by 2 is 4
