Answer:

Option D is correct.


a_3 = (-1)/(2)

Explanation:

The sequence is in the form of :


a_1, a_2, a_3, a_4, .......

where


a_1 represents the First term.


a_2 represents the Second term.


a_3 represents the Third term.


a_4 represents the Fourth term and so on.....

we have to calculate the
a_3 in the given sequence:

Given the sequence:
-4 , -2, -(1)/(2) , -(1)/(4), ......


a_3 = (-1)/(2)

Therefore, the third term
a_3 = (-1)/(2)
