Serial no in foreach loop with pagination

We can use foreach collection items index as serial no (SL) in pagination.

1...
2<th>Serial</th>
3 ...
4 @foreach ($products as $product)
5 <tr>
6     <td>{{ $loop->index + $product->firstItem() }}</td>
7     ...
8 @endforeach

it will solve the issue of next pages(?page=2&...) index count from continue.
