Question 5 (3 points)
Write the rule for the following geometric sequence:
1,1/3,1/9,1/27

The sum of the definite series is 1/2

Step-by-step explanation: A geometric series is written as  

{

a

,

a

r

,

a

r

2

,

a

r

3

,

a

r

4

,

.

}

, where  

a

is first term (of the series) and  

r

is the ratio of a term to its preceding term.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

5x+10 is the correct one

hope this
