$16, 48,80,112$

Work Step by Step

We know that the general formula of an arithmetic sequence is given by $a_n= a_1+(n-1) d$ The distance fallen from time $(n-1)$ to the time $n$ is given by $d(n)=D(n)-D(n-1)$ Thus, we have $d(n)=16n^2 -16(n-1)^2$ When we plug in $n=1,2,3,4$ we get $16, 48,80,112$
