## How do you find the sum of an even Fibonacci sequence?

A simple solution is to iterate through all prime numbers while the next number is less than or equal to given limit. For every number, check if it is even. If the number is even, add it to the result. Recurrence for Even Fibonacci sequence is: EFn = 4EFn-1 + EFn-2 with seed values EF0 = 0 and EF1 = 2.

### What is Fibonacci sum?

The list of Fibonacci numbers is given as 0, 1, 1, 2, 3, 5, 8, 13, 21, 34. On summation of numbers in the sequence, we get. Sum = 0 + 1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 = 88. Thus, the sum of the first ten Fibonacci numbers is 88. Example 2: Calculate the value of the 12th and the 13th Fibonacci numbers.

### What is the golden ratio and how do you calculate this number?

Two numbers are in the golden ratio if the ratio of the sum of the numbers (a+b) divided by the larger number (a) is equal to the ratio of the larger number divided by the smaller number (a/b). The golden ratio is about 1.618, and represented by the Greek letter phi, Φ.

What is the sum of the first ten 10 even Fibonacci numbers?
