Answer: Option G


a_6 = -2048

Explanation:

The geometric series have the following form:


a_n = a_1 (r) ^ {n-1}

Where
a_1 is the first term of the sequence and r is the common radius.

In this case we know that


a_1 = -2\\\\r = 4

So:


a_n = -2(4) ^ {n-1}

To find the sixth term
a_6, substitute
n = 6 in the equation.


a_6 = -2 (4) ^ {6-1}\\\\a_6 = -2 (4) ^ 5\\\\a_6 = -2048
