Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, …
By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

clear all; clc; close all; number_1 = 1; number_2 = 2; sum = number_1 + number_2; for i=1:(10-2) temp = sum; sum = sum + number_2; sum = temp + sum; end
clear all; clc; close all; first = 1; second = 2; sum = first + second; new_sum = 0; for i=1:(32-3) first = second; second = sum; sum = first + second; if(mod(sum,2) == 0) new_sum = sum + new_sum; end end % en bastaki 2'yi cift sayilarin toplamina katmadigindan sonda manual olarak toplamak lazim new_sum = new_sum + 2;
