Because its elements are related to the previous elements in a straightforward way, they are often defined using recursion. A drawing of the first 75 terms of Recamán's sequence, according with the method of visualization shown in the Numberphile video The Slightly Spooky Recamán Sequence [3]
This fact can be used to find the lcm of a set of numbers. Example: lcm(8,9,21) Factor each number and express it as a product of prime number powers. = = = The lcm will be the product of multiplying the highest power of each prime number together. The highest power of the three prime numbers 2, 3, and 7 is 2 3, 3 2, and 7 1, respectively. Thus,
s −2 = 1, t −2 = 0 s −1 = 0, t −1 = 1. Using this recursion, Bézout's integers s and t are given by s = s N and t = t N, where N + 1 is the step on which the algorithm terminates with r N+1 = 0. The validity of this approach can be shown by induction. Assume that the recursion formula is correct up to step k − 1 of the algorithm; in ...
This says that an expression is either a number, a product of two expressions, or a sum of two expressions. By recursively referring to expressions in the second and third lines, the grammar permits arbitrarily complicated arithmetic expressions such as (5 * ((3 * 6) + 8)), with more than one product or sum operation in a single expression.
Ackermann's original three-argument function (,,) is defined recursively as follows for nonnegative integers ,, and ...
The arrows indicate that the sequence comes from both the cell above, LCS(R 0, C 1) and the cell on the left, LCS(R 1, C 0). LCS(R 1, C 2) is determined by comparing G and G. They match, so G is appended to the upper left sequence, LCS(R 0, C 1), which is (ε), giving (εG), which is (G). For LCS(R 1, C 3), G and C do not match. The sequence ...

Only F sequences with (i,j) = (0,0), (0,1), (1,0), and (1,1), the first of which represents the original Q sequence, appear to be well-defined. [21] Unlike Q (1), the first elements of the Pinn F i , j ( n ) sequences are terms of summations in calculating later elements of the sequences when any of the additional constants is 1.
