The serial number not getting increment

Here is my code,

  <tbody>
    <?php $j = 1; ?>
    @foreach($items as $item)
    <tr>
      <td class="text-right"></td>
      <td></td>
      <td></td>
      <td></td>
      <td class="text-center"><a href="" class="btn btn-warning"><span class="glyphicon glyphicon-pencil" aria-hidden="true"></span></a></td>
      <td class="text-center">
        {!! Form::open([
          'method' => 'DELETE',
          'route' => ['Conversion.destroy', $item->id]
          ]) !!}

          {!! Form::button('<i class="glyphicon glyphicon-remove"></i>', array('type' => 'submit', 'class' => 'btn btn-danger')) !!}

          {!! Form::close() !!}
        </td>
      </tr>
      @endforeach
      <?php $j++; ?>
    </tbody>

When i execute this code, the serial number remains 1 for addition of more values.. For each and every value that has been added was with serial number 1.. How to get the increment of values like 2,3,4.. so on??
