Question

PLEASE HELP
Is this A, B, or C?

Answer 1

This is the sum of the first six terms of a geometric sequence. 
The sum can be written like this:
$-4\frac{1-\left(\frac{1}{2}\right)^6}{1-\frac{1}{2}}=-8\left(1-\dfrac{1}{2^6}\right)\\ =-8\dfrac{63}{64}\\=-\dfrac{63}{8}$
The correct answer is the second one.
