{\displaystyle \{1104,2208\}} , then An n-digit number N is a Keith Number if it forms a Fibonacci-like sequence that begins with the digits of the number itself. Loop for generating next terms of sequence and adding the previous ‘n’ terms. such that for They are computationally very challenging to find, with only about 100 known. n terms are the k If a Fibonacci-like sequence (in which each term in the sequence is the sum of the ‘d’ previous terms) is formed, with the first ‘d’ terms being the decimal digits of the number N, then N itself occurs as a term in the sequence. View Keith's age, phone number, home address, email, and background check information now. The special sequence has first n terms as digits of x and other terms are recursively evaluated as sum of previous n terms. Take the number 47 as it is written in base 10, and start a Fibonacci-like sequence from its digits : 4, 7, 11, 18, 29, 47, … 42, on the other hand, isn’t a Keith number: 4, 2, 6, 8, 14, 22, 36, 58, etc. Don’t stop learning now. {\displaystyle k=\lfloor \log _{b}{n}\rfloor +1} [1] ¹.
