Write a recursive formula for the sequence –2, 4, –8, 16, ...<br><br> please help and thank you
vaieri [72.5K]

Answer:

see explanation

Step-by-step explanation:

A recursive formula allows us to calculate any term in the sequence from the previous term.

These are the terms of a geometric sequence with r being the common ratio between consecutive terms.

r = 4 ÷ - 2 = - 8 ÷ 4 = 16 ÷ - 8 = - 2

Multiplying a particular term by - 2 gives the next term in the sequence.

Hence recursive formula is

a_{n+1} = - 2 a_{n} with a₁ = - 2

Does this set of ordered pairs represent a function? Why or why not?
belka [17]

Answer:

A

Step-by-step explanation:

Recall that for a function to be valid, each input value of x must give us one and only one unique output  value for y.

in this case we can see that one of the data sets is (3,-1)

which means that an input of 3 gave an output of -1

but we also see that another data set (3,1)

in this case an input of 3 gave an output of 1.

Because the same x input gives 2 different y outputs, this is not a function.

the answer is A

*ੈ✩‧₊˚<br> raise the fraction to higher terms as indicated <br><br> 2/3 to twenty-firsts
DIA [1.3K]

The appropriate fraction when the number is raised to higher terms will be 14/21.

<h3>How to compute the fraction?</h3>

It should be noted that when we sat raising that fraction to higher terms, it implies that changing the numerator and the denominator to higher numbers to reflect the fraction.

Here, the given number is 2/3. When it's raises higher, the appropriate fraction will be:

2/3 = x/21

x = (2 × 21)/3

x = 42/3

x = 14

Therefore, the fraction will be 14/21.

HELP PLEASE ASAP!!!!
vodomira [7]

Answer:

I may be wrong, but I learned that the first slot would be "terms". 4:3 would be an example of a ratio so it couldn't be ratio and a difference is subtracting.

The second slot would not be a geometric sequence because it is not correctly placed on the number line.

Therefore, the answers would be "terms" and "is not"
