With what speed should a body be thrown upwards so that the distances traversed in 5th second and 6th second are equal?

A body is thrown vertically upward with velocity u. The distance travelled by it in the 7^(th) and 8^(th) seconds are equal. The displacement in 8^(th) seconds is equal to (take g=10m//s^(2) )

With what velocity a ball be projected vertically so that the distance covered by it in 5^(th) second is twice the distance it covers in its 6^(th) second (g=10 m//s^(2))

A body is thrown vertically upward with velocity u . The distance traveled by it in the fifth and the sixth second are equal. The velocity u is given by

A freely falling body traveled xm in n^(th) second distance travelled in n-1^(th) second is

A freely falling body traveled xm in n^(th) second distance travelled in n-1^(th) second is
