The position function of a ball dropped from the top of a 210 meter tall building is given by s(t) = 210-4.9t^2 where position s is measured in meters and time is measured in seconds. Compute the average velocity of the ball over the given time intervals [4.99, 5]

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for
