How to write recursive and explicit equations

WebIn general, a recursive function where f ( n) = g ( n, f ( n − 1), f ( n − 2), …) can not always be converted to an explicit form. On the other hand, a recursive function in a computer program can be converted to a non-recursive (iterative) function. This is due to a rather trivial solution where the program's call stack is imitated in an ... WebSequence Calculator Step 1: Enter the terms of the sequence below. The Sequence Calculator finds the equation of the sequence and also allows you to view the next terms in the sequence. Arithmetic Sequence Formula: an = a1 +d(n −1) a n = a 1 + d ( n - 1) Geometric Sequence Formula: an = a1rn−1 a n = a 1 r n - 1 Step 2:

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. mary poppins public domain
