Answer:
-1/16, 1/32, and -1/64.
Explanation:
Basically, all you have to do is find the pattern in the sequence in front, which in this case is division by -2. Hence, you can apply this onwards to get (1/8) / -2 = -1/16, (-1/16) / -2 = 1/32, and (1/32) / -2 = -1/64.
Hope this helped! Merry Christmas!
