Answer:

62.5

Step-by-step explanation:

By dividing 50 by 10 and 10 by 2 we can find that <em>r</em>, or the common ratio is 1/5, meaning that this series converges, so it is solvable. The formula for a convergent series is \frac{a_{1}}{1-r}. By plugging in 1/5 for <em>r</em> and 50 for  a_{1} we can find that the sum of this infinite series is 62.5
