Final answer:
A closed formula, also known as an explicit formula, is used to solve a recurrence relation together with the initial conditions for the terms of a sequence.
Step-by-step explanation:
A closed formula, also known as an explicit formula, is indeed used to solve a recurrence relation together with the initial conditions for the terms of a sequence. This formula allows us to directly calculate any term of the sequence without needing to know the previous terms. It provides a clear and direct formulaic expression.
