5) Find the common ratio and the next term.<br> 512, 128, 32, 8,
serious [3.7K]

Answer:

The common ratio is \frac{1}{4}

The next term in the sequence is 2

Step-by-step explanation:

In a geometric sequence, the common ratio is the constant value you multiply a term by in order to find the value of the following term. Therefore, it is mathematically calculated as the quotient between a term and the term immediately before it. And it is in fact That is:

common ratio r=\frac{a_{n+1}}{a_n}

This quotient should be true for any two consecutive terms in the sequence.

so using the first two terms, we find:

r=\frac{a_{n+1}}{a_n}=\frac{a_{2}}{a1}=\frac{128}{512} =\frac{1}{4}

You can test that this common ratio is true for all other terms listed:

\frac{a_3}{a_2} =\frac{32}{128} =\frac{1}{4} \\\frac{a_4}{a_3} =\frac{8}{32} =\frac{1}{4} \\

So now, in order to find the term that follows, all we need to do is to multiply the last term given (8) by this common ratio:

a_5=8*\frac{1}{4} =2

URGENT, WILL GIVE BIG BRAIN OR WHATEVER ITS CALLED LOL
KATRIN_1 [288]

Answer: 10,500 hits

Step-by-step explanation:

I WANT BIG BRAIN! I WANT BIG BRAIN AHAHHHHHHH!!!!!!!

ok there are a number of ways to go about this

it is unclear whether or not the YT content creator will get one pound for 500 hits

i honestly dont know but i am going to assume it will

1000 times 20 (we are plugging in a test variable, 20, here)

so lets say we have 20,000 hits

lets divide that by 1000 and we get 20. 20 times 2 is 40 pounds so obviously thats too much

lets try 1000 times 10

so we have 10 times 2 and thats 20 pounds. we are closer

10,500 hits

(i put in 500 because half of 1000 is 500 and that will give you one pound instead of two)

WHAT IS THE EQUATION ?? AND TELL ME HOW YOU GOT IT.
kicyunya [14]

Answer:

x = 20

Step-by-step explanation:

the sum of the interior angles of a triangle is 180°

add expressions for each angle then combine 'like terms':

6x - 5 + 2x - 3 + x + 8 = 180

9x - 8 + 8 = 180

9x = 180

x = 180/9

x = 20
