General Doubt on Generating Functions
Given only a Generating Function in closed form can we find the sequence it represents? If so, how? Please explain with an example.If not, given a GF(closed form) in general what information does it convey to us about a series if the series is not provided ?

MadeEasy Full Length Test 2019: Combinatory - Generating Functions
Let We define Then ar is equal to. $\binom{r}{2019}$ $\binom{r}{r + 2018}$ $\binom{r}{2019 - r}$ $\binom{r}{r - 2018}$ Can anyone tell me if this type of question is in Gate 2019 syllabus or ... question in previous year question? If yes, then when can I learn this stuff from. Because I am unable to understand the whole solution.

MadeEasy Test Series 2019: Combinatory- Generating Functions
Let $M(x) = \frac{x^{2018}}{(1-x)^{2019}}$ we define $M(x) = \sum_{r=0}^{\infty}a_{r}x^{r}$ ,then $a_{r}$ is equal to- $A)\binom{r}{2019}$ $B)\binom{r}{r+2018}$ $C)\binom{r}{2019-r}$ $D)\binom{r}{r-2018}$
