Which of the following is NOT a type of democracy mentioned?

Participatory democracy is indeed a recognized form of democracy that emphasizes broad participation of constituents in the direction and operation of political systems. In a participatory democracy, citizens engage actively in decision-making processes, influencing policy and governance. It is often discussed in contrast to more representative forms of democracy.

The question asks for a type of democracy that is NOT mentioned in the context given. Indirect democracy, plebiscitary democracy, and direct democracy are also established categories. Indirect democracy refers to a system where representatives are elected to make decisions on behalf of the people, whereas direct democracy allows citizens to vote directly on issues.

In the context of various democratic theories and models, the inclusion of participatory democracy as an established category reflects its importance in contemporary discussions about enhancing democratic engagement and responsiveness to citizen needs. Thus, the notion that participatory democracy is not a type mentioned in the context of the question is inconsistent with its recognized status within democratic theory.
