Using Brown's criterion, it can be shown that the tribonacci numbers are complete; that is, every positive number can be written as the sum of distinct tribonacci numbers. Tribonacci Series : A Tribonacci sequence is a sequence of numbers such that each term from the fourth onward is the sum of the previous three terms.
