Quadratic Sequences (easy trick to find the nth term) | GCSE lockdown online learning

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

[@quangvupham7499]

this guy taught me more than my teacher :)

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.

[@kylefirth2400]

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

[@ludoxchiara]

i actually cannot express how thankful i am. was searching over a day to find a way to figure it out. lifesaver xx

[@josh82112]

This is so much better than the other methods teachers teach

[@gyu2220]

thank you so much for this. It took me so long to find an actual video to help me with understanding the sequence

[@chxwyRl]

THANK YOU SOOO MUCH!!! I HAVE A TEST TODAY LAST MINITE AND SAW WE HAD TO REVISE THIS THANK YOU SOOO MUCH MAN :)) ❤❤❤❤❤

[@ellanenninger5635]

absolute lifesaver

thank you so so much!!!!!❤

[@PaigeBotton-vm8dy]

Thank you this helped a lot

[@mariaadeel2423]

Thank you so much for this, I watched so many other videos yet this is the only one which tells us how to construct the individual equations and solve them

[@louis863]

Facts

[@v.player2925]

if the difference of the first difference in the quadratic sequences is two what should we do

[@kotjiiherunga4764]

Thank you so much.

[@sarahx3449]

So helpful, thx

[@chloedavidson2846]

Thank you so much

[@idek5014]

THANK YOU SO MUCH

[@sawdustwoodchips]

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.

[@dontwatchthatgril]

you’re wonderful

[@gamingate123]

thank you. so muchhh

[@alexthebruh]

Thanks so much ❤

[@noahmtb1358]

Didn't know how to find "b" thanks

[@PhilRZ9]

What if you get 1 as your second difference

[@dinohunter8676]

I wish you thought me, I would be so good at math

[@hiiralunaa]

why do we need to half it though?

[@rayzeon1263]

wowii, tysmm

[@itzy4541]

best video ever

[@sheunesumoyo9794]

Thanks you but can you clarify how to get three

[@ananmir2021]

YOUR BACK!!

[@ImranAli-on6es]

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

[@ayanoshorts2853]

liner sequences an=a1+(n-1)d

[@minaabdou4883]

Plz , why you should always use 3a+b = the first diff ?!

[@guuxofficial2325]

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

[@MathslearnCoUkvideos]

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

[@guuxofficial2325]

thanks teacher

[@whosminou]

by doing this in your exam and laying out working like this, would you still get the marks??

[@m4rzb4rz-qq3yq]

In abstract marks such as these, you might pick up marks depending on the examiner, mostly not though

[@asmafarooq.1292]

😊😊😊

[@stanepic999]

op man op

[@joliver1135]

im going to pass my test tmr

[@noname-nl5tm]

if thats true then why am i having troubles in finding nth term of 1,2,4,7,11

[@why3029]

grade 3 to grade 8

[@johnseers9008]

Last few seconds of video cut off.

[@amyhendri8665]
