if the sequence (2k-5),(k-4),(10-3k) forms an exponential sequence find the value of K and the distance metres through which a body falls aftert t seconds is given by d=8t^2. show that the distance through which it falls during the 3rd,4th, and 5th seconds forms a linear sequence?

(2k-5),(k-4),(10-3k)

T2-T1=T3-T2
k-4-2k+5=10-3k-k+4

-k+1=14-4k

3k=13

k=13/3
