Identify the missing term in the following geometric sequence:
4, -2, 1, -1/2, 1/4

a. 1/8

b. -1/8

c. 1/16

d. -1/16

B. -1/8

Step-by-step explanation:

Using the terms given in the sequence:

4, -2, 1, -1/2, 1/4

we can find the pattern by dividing since it is a geometric seqence:

-2/4 = -1/2

1/-2 = -1/2

-1/2 ÷ 1 = -1/2

So, each term is multiplied by -1/2 to get the next term in the sequence:
