Terviknumbrite

Terviknumbrite are a concept in recreational mathematics and number theory, referring to numbers that possess a specific additive property. A terviknumbrite is a positive integer such that when it is added to the sum of its digits, the result is a number that is also a terviknumbrite. This recursive definition implies a sequence of numbers where each subsequent number is generated by the process described.

The smallest terviknumbrite is 1. When 1 is added to the sum of its digits (which is also 1), the result is 2. Since 2 is also a terviknumbrite (2 + 2 = 4, and 4 is a terviknumbrite), the sequence continues. The sequence of terviknumbrite numbers begins with 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, and so on. This particular sequence consists of powers of 2, as each power of 2 is a terviknumbrite.

However, the definition does not restrict terviknumbrite numbers solely to powers of 2. Other numbers can also fit the definition. For instance, consider the number 19. The sum of its digits is 1 + 9 = 10. Adding 19 to 10 gives 29. If 29 is also a terviknumbrite, then 19 would be considered a terviknumbrite. To determine if 29 is a terviknumbrite, we add it to the sum of its digits: 2 + 9 = 11. 29 + 11 = 40. The process continues to check if 40 is a terviknumbrite. The exploration of terviknumbrite numbers often involves searching for these sequences and understanding their generative properties. The set of terviknumbrite numbers is infinite.
