What you need to do is know how many rows are in the repeater and loop through it without doing anything until you get to the last one.
if (have_rows('dizi_sezon_1')) {
// use get_post_meta
// it will return the number of rows in the repeater
$row_count = intval(get_post_meta($post->ID, 'dizi_sezon_1', true));
$i = 0;
while (have_rows('dizi_sezon_1')) {
$i++;
if ($i<$row_count) {
continue;
}
// will only get here on the last row
// put code here to display row
}
}
