What is the charge on both the ions? If you know that you can answer the questions.

What does the number in parentheses mean?

What is Ti?

BTW, you listed two different problems.

well you know Ti (II) has an oxidation number of 2 and Ti (I) has an oxidation number of 1.
Therefore the reaction is reduction, but i'm not sure which type of reduction.

Ti is an element belonging to a certain species of elements that only form one kind of ions. If you figure out the meaning of the roman numbers you can solve the problem.
