hi debjit625

You can construct a recurrence relationship like this:

Using this repeatedly on the LHS, you can write T10 in terms of T8, which you can write in terms of T6 and so on. Note that

So eventually you'll end up with a quadratic in Z, where all the terms cancel leaving zero as required for the RHS.
