**Tell us what’s happening:**

I am not understanding what the instruction is saying.

How is this test case returning… `fiboEvenSum(10) should return 188`

?

When the sum of even numbers in the first 10 numbers come out to be…

1, 2, 3, 5, 8, 13, 21, 34, 55, 89. 2 + 8 + 34 = 44.

Or If I add together even indexes…

1, 2, 3, 5, 8, 13, 21, 34, 55, 89. 1 + 3 + 8 + 21 + 55 = 88.

**Your code so far**

```
function fiboEvenSum(number) {
// You can do it!2+8+34+
return true;
}
fiboEvenSum(10);
```
