It starts with the lowest n-digit number (10 raised to n) and checks all numbers till the largest n-digit number. Now each subsequent term is the sum of the previous n terms, and the number N itself appears in this sequence. The happy number can be defined as a number which will yield 1 when it is replaced by the sum of the square of its digits repeatedly. 124; by SMC ACADEMY. It then computes the series using the sum of n previous numbers where n is the number of digits. Keith numbers are very rare and computationally difficult to find. If you seed it with the three digit number 197, then 197 will (possibly coincidentally) be seen as a Keith number. Learn how your comment data is processed.
