You start with two integers, usually 0 and 1 or 1 and 1 and get the next number in the pattern by adding the two previous numbers.
For example starting with 1 and 1 , 1 + 1 = 2 ,so the sequence is now
1 1 2 1+ 2 = 3 , so the sequence is
1 1 2 3 2+3 = 5 . " " " "
1 1 2 3 5
The formula is an = an-1 + an-2. where a0 and a1 are given and n > 1.
because, for instance, the number of petals on most types of flowers is usually a number that can be found in the Fibonacci sequence.
fibonacci sequence :)
The number 5 is a factor of every 5th number in the Fibonacci sequence. This is because every 5th Fibonacci number can be expressed as a linear combination of the Fibonacci numbers preceding it, and the pattern shows that they are all divisible by 5. For example, the 5th Fibonacci number is 5, the 10th is 55, and the 15th is 610, all of which are multiples of 5.
the first seven Fibonacci numbers are 1,1,2,3,5,8,13. 13 is a Fibonacci number.
