What is the 8th term of the geometric sequence with this explicit formula?
an = -)(n-1)
o
a. -1280
b. -640
o
c. 1280
o
d. 640

D

Step-by-step explanation:

To find the eighth term substitute n = 8 into the explicit formula

= - 5 × = - 5 × - 128 = 640 → D

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
