Suppose $\displaystyle a_1, a_2, 2, a_3, a_4$ be in an arithmetico-geometric progression. If the common ratio of the corresponding geometric progression is $\displaystyle 2$ and the sum of all $\displaystyle 5$ terms of the arithmetico-geometric progression is $\displaystyle \frac{49}{2}$, then $\displaystyle a_4$ is equal to $\displaystyle \_\_\_\_$.
