Evaluate using the finite geometric sum formula
Sever21 [200]

Answer:

S_9=-18.703.

Step-by-step explanation:

The given series is,

\sum_{i=1}^9(-\frac{1}{2})^{i-1}

When we substitute i=1, we get the first term, which is a_1=-28(-\frac{1}{2})^{1-1}


This implies that,

a_1=-28(-\frac{1}{2})^{0}


a_1=-28(1)=-28.


The common ratio is

r=-\frac{1}{2}


The finite geometric sum is given by the formula,

S_n=\frac{a_1(r^n-1)}{r-1} , -1\:.


Since there are 9 terms, we find the sum of the first nine terms by putting n=9 in to the formula to get,


S_9=\frac{-28((-\frac{1}{2})^9-1)}{-\frac{1}{2}-1}.


S_9=\frac{-28((-\frac{1}{2})^9-1)}{-\frac{1}{2}-1}.


S_9=\frac{-28((-\frac{1}{512})-1)}{-\frac{3}{2}}.


S_9=\frac{-28(-\frac{513}{512})}{-\frac{3}{2}}.


S_9=-28(\frac{171}{256}).


S_9=-\frac{1197}{64}.



S_9=-18.703.


The correct answer is B
