"Tribonacci Answer (1 of 2): The same way you code the Fibonacci sequence, just with one more term added to the recursive definition. Fibonacci formula: To figure out the nth term (xn) in the sequence this Fibonacci calculator uses the golden ratio number, as explained below: To determine the sum of all numbers until the nth term within the Fibonacci sequence first you should calculate the (n+2)th term in the sequence and then subtract 1 from it: Assuming we want to figure out the 25th number in the Fibonacci sequence and then find out the sum of all numbers until 25th term: This is because the 27th (25+ 2)th number is 196418, and if we subtract 1 from it we will get the right value 196417.
