WebSorted by: 23. The first two answers (oldest ones) are seemingly incorrect to me. According to this discussion which is already cited in one of the answers, sum of first n Fibonacci numbers is given by: SumFib (n) = F [n+2] - 1 (1) Now, lets define SumFib (m, n) as sum of Fibonacci numbers from m to n inclusive (as required by OP) (see footnote). WebJan 29, 2012 · Basically what you're doing here is adding every second element of the fibonacci sequence while the question asks to only sum the even elements. What you should do instead is just iterate over all the fibonacci values below 4000000 and do a if value % 2 == 0: total += value. WebJan 4, 2024 · There seems not to be a contest for this one yet. The task is simple. Add the first n numbers of the Fibonacci sequence that are even and output the result.
