Update accumulating column

Is there any way to approach this:

``` php
$queryBuilder->table('table')->where('id', '=', 1)->update([
    'number' => 'number' + 1
]);
```

So query would look like this:

```mysql
UPDATE table SET number = number + 1 WHERE id = 1;
```

Without having to use raw queries?

PD: I know doing `'number' + 1` is wrong, it is just a way to explain myself.
