Check If bootstrap last column is even or odd (using ACF custom field)

Question

Im using Acf Custom field in wordpress to get my custom field in Acf Reapter as below:

<?php if(have_rows('field_name')):?>
    <?php
        $i = 1;
        while(have_rows('field_name')):the_row();
        $total= count(get_field ('field_name'));
    ?>
        <div class="<?php echo ($i % 2 == 0 )?'col-md-6':'col-md-12'; ?>" id="<?php echo $i; ?>">
            <h1><?php the_sub_field('services_title'); ?></h1>

        </div>
    <?php $i++; endwhile; ?>
<?php endif;?>

so,i need following condition to be applied in this acf while loop:

i have bootstrap column in while loop, what i want is if bootstrap last column is odd then i want column to be 12 (col-12), i found the way to check number even or odd but want to check last number so if last number (last column) is odd i want column to be 12 else remain col-6 i have tried:

<div class"<?php echo ($i == (2 || 4 || 6) )?'col-md-6':'col-md-12'; ?>">
       display content there in while loop
    </div>

   <div class" <?php echo ($i % 2 == 0)?'col-md-6':'col-md-12'; ?>">
   display content there in while loop
    </div>
