Web27 jan. 2014 · As an example, consider this recursive function definition, which defines the Collatz sequence: f (1) = 0 f (2n) = 1 + f (n) f (2n + 1) = 1 + f (6n + 4) It's not known whether or not this is even a well-defined function or not. Were an algorithm to exist that could convert this into a closed-form, we could decide whether or not it was well-defined. Web16 dec. 2024 · 3. Recognize that any recurrence of the form an = r * an-1 is a geometric sequence. 4. Write the closed-form formula for a geometric sequence, possibly with unknowns as shown. 5. Solve for any unknowns depending on how the sequence was initialized. In this case, since 3 was the 0 th term, the formula is a n = 3*2 n. range electric cookers in blackWebExplicit formula: f (n) = 10 + 5 (n - 1) If you compare the term number with how many times the common difference, 5, is added, you will see a pattern for an explicit formula: To summarize the process of writing an explicit formula for an arithmetic sequence: 1.
