PLZ HELP MEDAL .. Consider the sequence 16, –8, 4, –2, 1, ...
a. Describe the pattern formed in the sequence.
b. Find the next three terms.

Answer 1

divide by -2 each time

Answer 2

-.5, .25, -.125

Answer 3

so -1/2, ...?

Answer 4

what did u divide by -2 first?

Answer 5

alternatively, you multiply by -1/2 each time

so the next 3 terms are: -1/2, 1/4, -1/8

since

1*(-1/2) = -1/2
-1/2*(-1/2) =1/4
1/4*(-1/2) = -1/8

Answer 6

divide by -2 each time
-.5, .25, -.125
For example, divide the number 16 by -2, you get -8. Now divide -8 by -2 and you get 4. The pattern is hard to grasp bc negative number and positive number become flipped when multiplying or dividing
