Even Fibonacci Numbers
Challenge 2
Each new number in the Fibonacci sequence is generated by adding the previous two Fibonacci numbers. For example by starting with the numbers 1 and 2 being the first and second numbers in the Fibonacci sequence, the first 10 numbers in the Fibonacci sequence looks like this:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89
The Exercise
You will be given a stub function in the file even_fib_nums.js. This function accepts one argument, maxFibValue which is a Number.
Remember, maxFibValue is the max value of a fibonacci number, it is NOT the Nth fibonacci number in the sequence.
You goal will be to sum up all the *Even Numbers that are less than or equal to, but does not exceed, the maxFibValue given to you.
Getting Started
- Fork and Clone this repository
- To install all dependecies, run the command:
npm install - Your work will be done in the file named:
even_fib_nums.js - Run your test with the command:
npm test - When you are done with the first 2 tests, un-skip the other by deleting
.skip. - The third test is broken, fix it!
Caveats
Remember, n is not how many numbers in the fibonacci sequence, it is the max value, the last term in a fibonacci sequence where you will then add up all even numbers.
