Thanks for the reply and support, I used array_filter() etc. from another tutorial which I came across.

I inserted the code you gave and got some errors and realised that it’s needed more code around it. I worked through some but now get;

Warning: count(): Parameter must be an array or an object that implements Countable in C:\laragon\www\joint-venture\wp-content\themes\joint-venture\single-house_types.php on line 15

Warning: count(): Parameter must be an array or an object that implements Countable in C:\laragon\www\joint-venture\wp-content\themes\joint-venture\single-house_types.php on line 15

With this code;

<?php if( have_rows('development_plot_number') ): ?>          
    <?php while( have_rows('development_plot_number') ): the_row(); ?>
		<?php 
			$development = get_sub_field('development', $post_id);
			$output = false;
			if (count($development) == 1) {
			  	$output = $development[0];
			} elseif (count($development) > 1)  {
				$last  = array_slice($development, -1);
				$first = join(', ', array_slice($development, 0, -1));
				$both  = array_merge(array($first), $last);
				$output = join(' and ', $both);
			}
			if ($output) {
			 	echo $output;
			}
		?>
    <?php endwhile; ?>
<?php endif; ?> 
<?php wp_reset_query(); ?>
