#2 a and b?

OpenStudy (anonymous):

a. 1/4

OpenStudy (anonymous):

How did you get 1/4?

OpenStudy (luigi0210):

Common ratio is .25

OpenStudy (luigi0210):

All the numbers in the sequence are divided by 4

OpenStudy (anonymous):

ok and do you guys know B?

OpenStudy (anonymous):

5/16, 5/64, 5/256

OpenStudy (anonymous):

And why are those the next 3 numbers?

OpenStudy (luigi0210):

The next 3 numbers, would be 5/16, 5/64, 5/256

OpenStudy (anonymous):

What did you do to get those next 3 number?

OpenStudy (anonymous):

try explaining why it is, instead of giving her the answer.

OpenStudy (anonymous):

@omoshiroi why is the next 3 numbers that?

OpenStudy (anonymous):

you have to use the common ratio on the next 3 set of numbers. What is the common ratio?

OpenStudy (anonymous):

.25

OpenStudy (anonymous):

correct but use the fraction 1/4. it is easier to work with fraction than decimals. multiply the common ratio by the last number in the sequence

OpenStudy (anonymous):

ok so i would do 5/4 times 1/4 to get one number and then do it 3 times?

OpenStudy (anonymous):

yes , So it would be 5/4 X 1/4 = 5/16

OpenStudy (anonymous):

then multiply 5/16 by the common ratio, and repeat.

OpenStudy (anonymous):

ok thanks!

OpenStudy (anonymous):

remember to only multiply the LAST number by the common ratio to get the next number

OpenStudy (anonymous):

ok
