Which geometric series converges?

The behavior of the terms depends on the common ratio r: If r is between −1 and +1, the terms of the series approach zero in the limit (becoming smaller and smaller in magnitude), and the series converges to a sum. In the case above, where r is 1/2, the series converges to 1

YES the answer that you chose is correct the 1st one because each of those fractions are multiplied by 1/2
