The formula for the sum of geometric series = a (1 - r^n) / 1 - r
when it will be an infinite geometric series. the term r^n will equal to zero because and number < 1 that is raise to the power infinity the answer is zero that is why in a infinite geometric series, sum = a / 1 - r.
if the r < 1 then there will be no numerical answer because the sum will be infinity. that is why r < 1 to have a sum

If the arrow is in the air, then when it hits the ground, h(t)=0. So:
0=-16t²+63t+4
16t²-63t-4=0
(16t+1)(t-4)=0
t= -1/16 or 4
Using the positive result of 4, we get t=4 seconds as the time the arrow was in the air
