A sequence is defined by the recurrence relation u_n+1 = 1/3 u_n + 10  with u₃ = 6 . Find the value of u₄ and the limit of the sequence.

To find ...

It must firstly be noted that, in general, the work done on an object is equal to its gain in energy.The trolley has gained kinetic energy. This can be calculated using the formula: "KE = (1/2)mv^2&q...
