<h2>Answer:</h2>

The sequence that could be partially defined by the given recursive formula is:

           -10, -7.5 , -5 , -2.5 ,........

<h2>Step-by-step explanation:</h2>

We are given a recursive formula as:

                  f(n+1)=f(n)+2.5 for n≥1

Hence, from the given options we will check the difference of which sequence is: 2.5

A)

   2.5, 6.25, 15.625, 39.0625, …

6.25-2.5=3.75

15.625-6.25=9.375

As we could see that the common difference is not 2.5

Hence, option: A is incorrect.

B)

        2.5, 5, 10, 20

5-2.5=2.5

10-5=5

20-10=10

As the common difference is not 2.5.

Hence, option: B is incorrect.

C)

               –10, –7.5, –5, –2.5, …

-7.5-(-10)=-7.5+10=2.5

-5-(-7.5)=5+7.5=2.5

and -2.5-(-5)=-2.5+5=2.5

As the common difference is 2.5.

           Hence, option: C is correct.

D)

     -10, -25 , 6.25 , 156.25

-25-(-10)=-25+10= -15

As the common difference is not 2.5

Hence, option: D is incorrect.

Is defined by the formula because the next term can be obtained by adding 2.5 to the current one.</span>

Help! This is so confusing please
Rus_ich [418]

Given equation is f(x)=6^x

Now it says to find f(2)

that simply means plug x=2 because we see that 2 is written in place of x in f(x) and f(2)

f(2)=6^2

f(2)=6*6

f(2)=36

Hence final answer is f(2)=36
