Which of the following methods of amending and revising the constitution are not used in texas?

The "initiative method" is not used in Texas and the "conventional method" is not used either.

Explanation:

The initiative method is a method by means of which an amendment to the state constitution is proposed by a petition signed by voters who represent 8% of the votes for all candidates for governor at the last election held in the state.

Through the "conventional method", a convention must be called by a majority vote of voters so as to propose an amendment.

In Texas, the only method that applies so as to amend and revise the constitution is the "legislature method". In other words, the legislature is the body empowered to make an amendment to the Texas Constitution in a regular or special session. Proposed amendments must be approved by a majority of voters in a referendum.
