Finding a closed-form expression for a sum.
What happens as n goes to infinity?
Geometric series in general The sum of a series is defined as a limit of partial sums, which means that when the ratio r satisfies −1

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
