Final answer:
The question concerns finding the nth term of a sequence or series related to velocity, in this case defined as vn. The lack of an explicit formula or progression method hinders providing a concrete numeric answer. Examine your materials for the relevant vn definition to utilize the provided 'n' value.
Step-by-step explanation:
Based on the problem given, we are looking at a problem based on sequences or series, particularly in mathematical notation related to velocity. Closing velocity or nth iteration suggests that this problem deals with the computing a series' specific term value, or the nth term, in a physics context, as velocity is involved. Primarily, it should be noted that without more information on the specific formula or method being used to calculate the vn, it is not possible to provide a definitive numerical value. Ensure you have a clear definition of the velocity term formula to apply the given 'n' value.
