**Tell us what’s happening:**

My initial solution created an array which I then called `.reduce()`

on to sum the even valued terms. But that would not pass. I then used the code shown here to pass the challenge. However shouldn’t the first returned value be 44 and not 188; as 144 is the 11th term and shouldn’t be summed, or?

I am a math noob but am really confused by this.

**Your code so far**

```
function fiboEvenSum(n) {
let a = 1
let b = 1
let c
let num = 0
while ( n >= 0) {
c = a
a = a + b
b = c
n--
if (c % 2 == 0) {
num += c;
}
console.log(num)
}
return num;
}
fiboEvenSum(10);
```
