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 . By plugging in 1/5 for <em>r</em> and 50 for we can find that the sum of this infinite series is 62.5
So the 4ft mailbox’s shadow was six feet. That 2ft longer. According to my logic if the tree had a showdown of 36ft we subtract 2ft. The trees actual size is 34ft.
