Answer 1

You can't mix <?php into echo -- that's used for getting back into PHP execution mode when you're outputting raw text, but you're already in PHP execution.

Since bloginfo() echoes its output instead of returning a string, you need to split this up into multiple statements.

<?php 
echo '<a href="?cat='.$term->term_id.'"> <i class="fa fa-youtube-play fa-5x" aria-hidden="true"></i> <img class="img-responsive" src="';
bloginfo('template_url');
echo '/images/'.$term->name.'.png" alt="'.$term->name.'"> </a>'; 
echo "</div>";
