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