Let us start from your last equation, and focus specifically on the expectation. Assuming that the end date of each period is the start period of the next, the idea is to simplify it using conditional expectations. Since $t < t_{n-2}$, we can write using the tower property of conditional expectations:  \begin{aligned} \Bbb{E}_{t}^{Q^{t_n}} \left[\prod_{...
