In order to predict the products in an organic reaction scheme, one must understand the role of the reagents involved in the reaction.
In the first step, LDA is used in the presence of THF. Here, LDA is used as a base, which means it'll draw out a proton from the ketone reactant, leaving behind an enolate form which would then interact with CH3I in the second step.
In the second step enolate form of the reactant would act as a nucleophile and the carbon in CH3I would act as an electrophile, also, I- is a good leaving group.
The interaction and the reaction mechanism with the expected product are in the image given below:
