The distance a freely falling body covers in the nth second is given by
s(n)=d(n)-d(n-1). show s(n) in terms of g, in simplified form.

prove that the quantities s(n) form an arithmetic sequence

and you

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

The answer to the question is d
