Given 2 integer numbers we can calculate their average like this:

```
return (a+b)/2;
```

which isn’t safe since (a+b) can cause overflow (Side Note: can someone tell me the correct term for this case maybe memory overflow?)

So we write:

```
return a+(b-a)/2;
```

can the same trick be implemented over `n`

numbers and how?
