The trick to finding the nth term for quadratic (and linear) sequences
Make grade 8 maths easy and accessible, essential maths revision
For linear sequences
a is always the common difference
a+b always add to the first term
For quadratic sequences:
This shows how a is always half the 2nd difference
3a+b is always the first 1st difference
a+b+c is always the first term

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

I’m not even close to doing my GCSEs. I just randomly clicked on this video and it made quadratic sequences SO much simpler! Thank you man.😅 I‘ll defiantly have a headstart of this topic.

Good video. I feel like every time I forget how to solve a quadratic sequence I go on to KZfaq 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.

im in year 8 i think thats 7th grade in america and my teacher taught me like this too luckily, i already understood it but i was intrigued and clicked on this vid. Btw if you are wondering why we are doing this work at a young age its because im in the highest set and do higher level work , why did u waste your time reading this lol

Hello teachers I'm you student i want understanding the meaning of 3n+?

@MathslearnCoUkvideos 3 жыл бұрын

The sequence 3n represents 3*1=3 3*2=6 3*3=9 3*4=12 3*5=15 It is basically the 3 times tables So it represents the sequence 3, 6, 9, 12, 15... So 3n+? is the sequence above with an additional number added on so 3n+2 would be 2 more than the above sequence ie (so 2 more than the 3 times table) 5, 8, 11, 14, 17 etc... It still goes up by 3, but starts at 5 rather than 3
