this trick is fully a god send. My teacher taught us "his way" which took him 20-30 mins to go through. You taught it to me in 5. Respect brother

Good video. I feel like every time I forget how to solve a quadratic sequence I go on to YouTube and find a different method :)

Nice. Would be good to explain where these ‘tricks’ come from. Too many students I teach have been given tricks but no understanding of why.
