The 8th term of the Fibonacci sequence is 21. The Fibonacci sequence is a series of numbers where each number is the sum of the two that precede it. The first two terms of the Fibonacci series are usually 0 and 1, but some sources start with 1 and 1 instead. The sequence goes as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... . To find the nth term of the Fibonacci sequence, we can use the formula f(n-1)+f(n-2) .
