Choose a term count and inspect the sequence starting with 0 and 1.
The Fibonacci Sequence Generator lists terms of the sequence that starts with 0 and 1. Choose a count to inspect the pattern or prepare a reference for a coding exercise.
Each term after the first two is the sum of the two before it: 0, 1, 1, 2, 3, 5, 8, 13, and so on. It is a useful example for comparing iteration, recursion, and memoisation.
100, 1, 1, 2, 3, 5, 8, 13, 21, 34The additions begin 1+0=1, 1+1=2, 2+1=3, and 3+2=5, continuing to 34 in this example.
Do not assume unlimited terms or exact large-integer output. Use a manageable count and check precision separately if you need every digit of a large term.
Ratios of consecutive nonzero terms approach the golden ratio, about 1.618. For example, 34 divided by 21 is about 1.619. You can use the generated list to explore that relationship without treating a rounded ratio as an exact value.
