Since he cycles 1 km for each trip, he will have cycled 21 km after 21 trips.
Add this to his existing amount of km:
28 + 21
= 49
So, he will have cycled a total of 49 kilometers
By the ratio test, the series diverges since the limit

is not finite.
The series only converges for x = 1/4.
Answer: D
To show work is plug the the x-coordinates for the points given.
Example:
x=2
y=-(1/4)x^2
y=-(1/4)2^2
y=-(1/4)4
y=-1
