what is fibonacci number?
user
the fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers. the first two numbers in the fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two. so the next number in the sequence would be 1+0=1, followed by 1+1=2, then 2+1=3, and so on. the fibonacci sequence is named after the italian mathematician leonardo of pisa, who introduced the sequence to european mathematics in the 13th century.
