Answer:
Option D is correct.
[tex]a_3 = \frac{-1}{2}[/tex]
Step-by-step explanation:
The sequence is in the form of :
[tex]a_1, a_2, a_3, a_4, .......[/tex]
where
[tex]a_1[/tex] represents the First term.
[tex]a_2[/tex] represents the Second term.
[tex]a_3[/tex] represents the Third term.
[tex]a_4[/tex] represents the Fourth term and so on.....
we have to calculate the [tex]a_3[/tex] in the given sequence:
Given the sequence: [tex]-4 , -2, -\frac{1}{2} , -\frac{1}{4}, ......[/tex]
[tex]a_3 = \frac{-1}{2}[/tex]
Therefore, the third term [tex]a_3 = \frac{-1}{2}[/tex]
