What is the sum of an infinite geometric series if the first term is 8 and the common ratio is 1⁄2?
a. 8
b. 16
c. 32
d. 4

  B.  16

Step-by-step explanation:

The sum is given in terms of the first term a1 and the common ratio r as ...

  S = a1·1/(1-r)

Substituting the given values and doing the arithmetic, we find ...

  S = 8/(1 -1/2) = 16

The sum of the series is 16.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.
