1 - First term = 3 / 49

 

2 - The value of r = 13 / 49

 

3 - The value of r tells you that the series converges. In fact, it converges to = 1 / 12

 

4 - Here are the first 5 - 6 terms of the series: 3/49,   39/2401,   507 / 117649,   6591 / 5764801,   85683 / 282475249,   1113879 / 13841287201...etc.
