Sep 11, 2023 · A n digit number x is called Keith number if it appears in a special sequence (defined below) generated using its digits. The special sequence has first n terms as digits of x and other terms are recursively evaluated as sum of previous n terms. The task is to find if a given number is Keith Number or not. Examples:
A positive n digit number X is called a Keith number (or repfigit number) if it is arranged in a special number sequence generated using its digits. The special sequence has first n terms as digits of x and other terms are recursively evaluated as the sum of previous n terms.
In recreational mathematics, a Keith number or repfigit number (short for repetitive Fibonacci-like digit) is a natural number in a given number base with digits such that when a sequence is created such that the first terms are the digits of and each subsequent term is the sum of the previous terms, is part of the sequence.
A Keith number is an n-digit integer N>9 such that if a Fibonacci-like sequence (in which each term in the sequence is the sum of the n previous terms) is formed with the first n terms taken as the decimal digits of the number N, then N itself occurs as a term in the sequence.
May 13, 2021 · A positive n digit number x is called a Keith number or repfigit number (repetitive Fibonacci-like digit) if it is arranged in a special number sequence generated using its digits. This sequence has n terms as digit of x and the next term is determined by the sum of previous n terms and so on.
In recreational mathematics, a Keith number or repfigit number (short for repetitive Fibonacci-like digit) is a natural number in a given number base with digits such that when a sequence is created such that the first terms are the digits of and each subsequent term is the sum of the previous terms, is part of the sequence.
May 21, 2023 · A Keith Number is a special type of number that possesses a distinct property: its digits combine in a unique way to generate a new sequence of numbers. The algorithm for generating Keith Numbers involves summing up the previous occurrences of the number’s digits, creating a new number in the sequence.
