I want to display my 2. latest post

Try below code:
It will display the second and third latest posts.

$the_query = new WP_Query(array( 'post_type' => 'post',
'post_status' => 'publish',
'order' => 'DESC',
'posts_per_page' =>'2',
'offset' => 1
));


if ( $the_query->have_posts() ) : 
   while ( $the_query->have_posts() ) : $the_query->the_post(); 

     the_title(); 
     the_excerpt();

   endwhile; 
  wp_reset_postdata(); 

else : 
     __('No post found');
endif;
