Answer
Use letters to represent each simple statement in the argument.
p: Argument is in the form of the fallacy of the inverse.
q:Argument is invalid.
Express the premises and conclusion symbolically as:
\[\frac{\begin{align}
& p\to q \\
& q \\
\end{align}}{\therefore p}\ \ \ \ \ \ \frac{\begin{align}
& \text{If an argument is in the form of the fallacy of the inverse, then it is invalid}\text{.} \\
& \text{This argument is invalid}\text{.} \\
\end{align}}{\therefore \text{This argument is in the form of the fallacy of the inverse}\text{.}}\]
The argument is in the form of Fallacy of the Converse.
So, the argument is invalid.
