Two quick changes before diving into action:
First of all, we can factor the 100 out of the sum:
Secondly, we can see that the index k starts from 1, but the exponent is k-1. This means that when k=1, the exponent is actually 0. When k=2, the exponent is actually 1, and so on. So, we can rewrite the sum as
Now, let's focus on the sum. First of all, it converges, because every sum like
converges if and only if , which is the case because
Also, in this case we have
so in your case you have
and let's not forget the 100 we factored at the beginning!
C is the answer because there is no variable for X which without it would make a horizontal line.

The correct answer is A) it would be to the left of zero on the number line.
Positive numbers are to the right of zero on the number line.
The opposite of a positive number is a negative number.
Negative numbers are to the left of zero on the number line.
