Modifying an element of a list in a function

I'm using exactly the same logic as the example in the exercise. The print out that I get is correct : [3, 8, 7] but I get the error message Oops, try again. list_function([4, 3]) returned [3, 11, 7] instead of [4, 6]

```
Replace this line with your code.
def list_function(x):
n[1]=n[1]+3
return n
n = [3, 5, 7]
list_function(n)
print n
```
