Hey /prog/, I know I'm a little late to the party, but I was wondering how many problems you've solved thus far.
Other discussion regarding Project Euler is also welcome!
>Problem 2
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, ...
Find the sum of all the even-valued terms in the sequence which do not exceed four million.[/o] In[2]:= n = 1; While[Fibonacci[3 n] < 4000000, n++]
Sum[Fibonacci[3 m], {m, n}]
Out[2]= 19544084
