answer: if sn is the distance covered by a body in n- Seconds and sn_1 is the distance covered by the body in n_1 seconds then,
S nth = Sn_Sn_1
since we have
s = ut + 1/2 at^2
if t=n then,
Sn =un +1/2 an^2
- if t=n-1 then,
Sn-1 = u(n-1) +1/2a( n-1) ^2
subtracting 2 from 1 we get
Snth= un +1/2an ^2 _ ( u(n-1) +1/2 a (n_1)^2 )
