I've found this question across my JLPT N4 practice

1) 楽しかったですよ。参加(できなくて/できないので)、残念でしたね.

The answer is できなくて What are the differences between ので and て in usage for reasonings?

    But it doesn't look like a test on the difference between the two forms, but rather on tense agreement. – macraf Sep 25 '17 at 1:23

The の simply adds an explanatory tone to the sentence.

今忙しいので、どうぞお先に行ってください。 (As I am) busy right now, please go on ahead.

But I think you're veering away from the original grammatical matter being tested in your practice sentence. macraf is giving you a good hint.
