Question

Find the common ratio of the sequence.

–164, –82, –41, –20.5, . . .

Answer 1

Pick any term you want except for the first term. Divide this term by the previous term.

Answer 2

oh okay i did it a different way and couldn't figure out what 10 1/4th would be so i just clicked 1/2.. comes to find out 2-20.5/-41= 1/2 :)

Answer 3

what that work shows is that you're dividing each term by 2 to get the next term

notice how

(2nd term)/(1st term) = (-82)/(-164) = 1/2 = 0.5

Answer 4

that's an interesting way to get the answer

Answer 5

Yeah thats what I figured out above :)

Answer 6

`so 10 1/4 does = 1/2?` idk what you mean here

Answer 7

10 1/4 is not equal to 1/2

Answer 8

but yeah the common ratio is 1/2 or 0.5

Answer 9

ohh

Answer 10
