Answer:

The 8th term = -4,096

Explanation:

Given:

¼, -1, 4, -16, . . .

Required:

8th term of the sequence

Solution:

1st term = ¼

Common ratio = -1/¼ = 4/-1 = -16/4 = -4

Desired term = 8

Plug in the values into the formula given:

(1)/(4) * -4^((8 - 1))

(1)/(4) * -4^(7)

(1)/(4) * -16,384

(-16,384)/(4)

= -4,096
