ticle moving in a straight line is observed to be at a distance 'a' from a marked point initially, at a
ce 'b' after an interval of n seconds, to be at a distance 'c' after 2n seconds and at a distance 'd'
In seconds. Prove that if the acceleration is uniform, d-a=3(c-b) and that the acceleration is equal
a-26
