The answer is -143,231.
The first step to solving this problem is to find all terms in the sequence. Since this is a geometric sequence, the next term can be found by multiplying the current term by the common ratio.
That means that the second term can be found by: -11×-5 = 55
And the third term can be found by 55×-5 = -275
And so on...
Here are all seven terms:
-11, 55, -275, 1375, -6875, 34375, -171,875
The next step is to add them all up to find the sum which end up as -143,231, which is your final answer.
