Fibonacci numbers define a sequence of integers where, after two starting values, each number is the sum of the two preceding numbers. The first two Fibonacci numbers are defined to be 0 and 1, giving the sequence
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...
Sometimes a definition is seen where the first two numbers are 1 and 1 (ignoring the zero).

A Fibonacci sequence is one where the second number is equal to the first and all subsequent numbers are the sum of the preceding two.
A sequence does not have to start with 1.
4, 4, 8, 12, 20, 32... is a Fibonacci sequence

Its when after the first 2 numbers, the previous 2 numbers add up to the sum of the first 2, and so on...
0, 1, 1, 2, 3, 5, 8, 13, 21, and so on.

The Fibonacci number sequence (1,2,3,5,8,13,21,34,55,89,144,...) is derived by adding the first two numbers to arrive at the third. The ratio of any number to the next number is 61.8 percent, which is frequently characterized as a major Fibonacci retracement number. The inverse of 61.8 percent is 38.2 percent, also characterized as a major Fibonacci retracement number.

Fibonacci numbers are generated by the following recurrence relation:
f(1) = 1
f(2) = 1
f(n+2) = f(n+1) + f(n).
That is each number is the sum of the previous two.

It looks like all of the above are correct, but you may wish to check here for additional information as to their origins etc

The Fibbonacci sequence begins with 0, 1 and continues by adding the las two numbers to create the next number. So:
0,1,1,2,3,5,8,13,21,34,55...................
