​ −1/4

​ −3 ​

−4

​ −1/2 ​

Answer 1

-1/2

Explanation:

took the test on k12 and got this question correct

Answer 2

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)`
