return current fragment index Fragment Pager Aapter

I'm using a fragment Pager Adapter, but i need to know in which fragment i am, im trying to deploy different information on the fragment based on the index of it, is there a way to get its index or something that i could use to differentiate which fragment is showing?

this is what im using to instantiate my fragments:

private void initialisePag(Integer RSize) {
        final List<Fragment> fragments=new Vector<Fragment>();
        for(int i = 0;i<RSize;i++)
        {
            fragments.add(Fragment.instantiate(this, fragment1.class.getName()));
        }

        pagerAdapter=new pagerAdapter2(this.getSupportFragmentManager(),fragments);

        ViewPager pager=(ViewPager)findViewById(R.id.view_pager2);
        pager.setAdapter(pagerAdapter);
    }

also this is my adapter :

public class pagerAdapter2 extends android.support.v4.app.FragmentPagerAdapter {

    private   List<Fragment> fragments;

    public pagerAdapter2(FragmentManager fm,List<Fragment>fragments) {
        super(fm);
        this.fragments=fragments;
    }

    @Override
    public Fragment getItem(int arg0) {
        return this.fragments.get(arg0);
    }

    @Override
    public int getCount() {
        return this.fragments.size();
    }
}

You can call the getCurrentItem() method on the ViewPager to find out the position of the currently displayed fragment :

int index = pager.getCurrentItem();
