3,-12,48,-198 whats the next 3 numbers

OpenStudy (anonymous):

you got this one right? ignore the negative sings for now, they look like they are in a pattern of +, -, +, -, +, - ...ad infinitum

OpenStudy (anonymous):

yeah I did get the other one it wouldnt let me post after

OpenStudy (anonymous):

you can refresh the page then post if that happens...

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

so assume, the numbers are all positive for now...each value is larger than the next, how much larger though? just check out the first 2 values and see what you think the relationship is between them, how do you get from 3 to 12?

OpenStudy (anonymous):

you multiply 3 times 4

OpenStudy (anonymous):

all right, now 12 and 48.?

OpenStudy (anonymous):

12 times 3

OpenStudy (anonymous):

4 i meant

OpenStudy (anonymous):

is the last number actually -198? or -192?

OpenStudy (anonymous):

-192 yea

OpenStudy (anonymous):

all right, so assuming all numbers are positive, after 192 is ____, then ___, then ___

OpenStudy (anonymous):

do you mutiply 192 times 4

OpenStudy (anonymous):

right on, so that's part of the pattern, the full relationship also needs the +, - pattern....so apply the *4 and the sign changes and then post the pattern
