To find the value of a₃ in the sequence −4, −2, −1/2, −1/4, ..., we need to determine the pattern in the sequence.
If we look closely, we can see that each term is obtained by dividing the previous term by 2.
So, starting with −4, we divide by 2 to get −2, then divide −2 by 2 to get −1/2, and so on.
Applying this pattern, we can find the value of a₃:
a₃ = (-1/2)/2 = -1/4
What is the value of a3 in the sequence?
−4, −2, −1/2, −1/4, ...
