This recurrence relation has got at least two problems as far as the study design is concerned.
First, and significantly, it is not a first-order recurrence relation and so is not withing the scope of the curriculum.
U(n+1) is two terms beyond U(n-1) and I thinke there is only enough information given to find U(3), U(5), U(7)  etc. The even-numbered terms within the first seven could only be found if a second "initial" term was given given.
Second, the initial term should be written before the rule, not after it, and should usually be U(0) rather than U(1) but someone may have tried to avoid U(n-1) representing a term called U(-1) as a first term.
