Answer 4

k

Answer 5

well it is going down so which means it is i beileve subtracting hree give me one moment >:) k

Answer 6

okay:)

Answer 7

I believe that each number is multiplied by -0.5.

Answer 8

so first thig you want to do is find out what the pattern is so it is subractig and plus ok
so its going 16-8=8,
8-4=4,
then 2-1=1
so its really going from 16,8,4,2,

then let me give u the nesxt art of the problem>:)

Answer 9

ok so to find the next three terms we know that they will be all three negatives so give me a moment to map this part out k

Answer 10

becasue 1 then its 0 so what happens thye are neg's so just sthink abiout that part and let me get the rest going here thse kind of problems must need a workout and using your thinking time yes i know its hard sometimes casu im doing the same thing heree in school now

Answer 11

but how do you figure out the patterns afterward?

Answer 12

are they all 0's?

Answer 13

yes thats what im trying to figure out also lol here becasue when it turns from the 1 its negative's so whihv means you haev to go abck from the numbers

Answer 14

no

Answer 15

becasue then that wouldn't be a pattenr here lol

Answer 16

lol true:)

Answer 17

To find the next three terms you would carry on with the pattern of the sequence that you found in the first part. So each term is being multiplied by -0.5, so to find the next term you would multiply 1 by -0.5.

Answer 18

i did that and it kept saying "-0.5"

Answer 19

yes there you go thankyou @jamie133

Answer 20

yes ok so are you mutiplying the numbers

Answer 21

yes ok so what would be your next answer after 0.5

Answer 22

-0.5

Answer 23

Yup, so the next term would be -0.5.
then do (-0.5)*(-0.5) to get the next term, and so on (:

Answer 24

ohhh , i understand ! thank you =)

Answer 25

yes jsut mutiply the next like she said -0.5 times that number again to find the next term.thenn....

Answer 26

i got 0.25 and then -0.125 :)
