@register.filter
def adjust_for_pagination(value, page):
    value, page = int(value), int(page)
    adjusted_value = value + ((page - 1) * settings.RESULTS_PER_PAGE)
    return adjusted_value

# And the template snippet:
{% for object in object_list %}
<div class="serial-no">
    {% if is_paginated %}
        {{ forloop.counter|adjust_for_pagination:page }}
    {% else %}
       {{ forloop.counter }}
    {% endif %}
</div>
...
{% endfor %}

Can be achieved with:

{% for object in object_list %}
    {{ page_obj.start_index|add:forloop.counter0 }}
{% endfor %}

Thanks for pointing that out. I'll have fun removing that code from my repo ;)
