Hello Mr Jeffery. I need to say my thanks, 2 years ago I was planning on studying PPE at York university. I needed to increase my B grade GCSE to and A grade in maths. I had to accomplish this while doing an access course. I was in a position where I had to learn GCSE maths 6 years after I had left secondary school, to an A grade standard, in less than 3 weeks. Your videos plus help from a friend allowed me to accomplish the impossible. Mr Jeffery, I can't thank you enough. I'm glad to see a new video posted, and I wish you all the success in the future sir.
That's great to hear. Thanks for taking the time write such a lovely message. :)
Mr. Jeffery, I would really like to thank you for this. I have a small math quiz tomorrow and I forgot how to do everything. I was kind of freaking out cuz all the other videos were completely useless but you, are a absolute legend.
Sir, thank you. You've just made life a lot easier for this potential medical student
Hello sir! Thank you for this lovely video. At the end, on question (e) I did 51-31 which = 20. 20-17 = +3 and not +6 as all the other numbers follow the pattern of +6. Sorry if i may be wrong.
you my friend are a legend, iv watched about 5 diffrent videos which didn’t help atall, now i understand cheers mate
THANK YOU!!! i had no idea how to do this but you made it SO simple. i watched 5 vids before you and this was the one!
Thank you so much Mr Jeffery..
I have never really understood this topic but after watching your video, I now get the concept..
I can't believe this !! I have been struggling for so long and got soo low marks in sequence and I hated this lesson too but as I have my o' levels I saw many videos for Quadratic sequence but never understood any of them then I came across ur video ..and like within 5 sec I just understood the whole SEQUENCE LESSON ..I am able to do really well in sequence and feeling so happy .ALL THE CREDIT GOES TO MR JEFFERY.Thank YOU so much! plz, keep making more videos don't stop it "U R A REALLY GREAT TEACHER." THANKS ONCE AGAIN :)
Get this man a raise!
This is the best explanation out of them all. Well done!
Thanks it really helpful I have my math Mok exam coming up and this it the only video I found it helpful.
Thank you for this - you've just made a new concept click in my mind. Well done.
Great video, after so many videos i finally understood! Thankyou!
I love this video. Thank you Mr Jeffrey.
Very helpful and clear explanation . Thank you so much ~
Thank you sooo much for this video, I finally understand quadratic sequences, you explain them so well!
love this video, questions well explained, this channel is highly recommended by an Asian
Thank you! I'm doing this in school rn so this is a big help! :D
Very clear examples. Thanks a lot!
thank you so much very helpful. didn't understand until now. Work for lockdown XD
love to see u back 👍
sir i swear you deserve more subs
THANK YOU SOOOO MUCH. helped a lot!!
This is really helpful. Thank you.
Excellent video 👍👍👍
bravo
God! Finally i understand (I'm risky when it comes to algebra) so thank you so much :D
I got it with a few slips of the tongue at the end with the second example 😜. It's not confusing and I believe most will get it. Thanx.
Thank you so much
You’re a legend
great sir 👍👍
Thankyou you're awesome!
Thanks alot .
It was really helpful
Thanks Mr Jeffery :D
LIFE SAVER OMG
Good explanation ty
Thanks you saved me
Excellent video. Last term on (e) should be 54.
Thank you alot you relly help me 👏
in question e. i believe 51 should be 54 because when i computed the second diff. +6 +6 +3 this is what ive found sorry if im wrong
THANK YOU BIGMAN
i think something is wrong question E . the last term is 51 instead of 54
Thank you so much!
omg thanks m8. ur awesome
Hi sir, how is The Boswells School going . I am your old year 11 student. I like the way u teach in the videos keep making same videos thank you.
This one also helped
6.11.17.Mat125 at Salemu.edu
none of the 13 students & instructor E. Asher has NO notion on how to do the Quadratic Sequences that was provided here in this video
GOAT
Thank you so mucih
im still stuck (im bad at maths)
Last ques o.5 -0.5=0
Therefore difference should be 0 instead of 1
I think the 5th term for e) should be 54 not 51. Does anyone agree?
question why is it -5n not +5n
absloute legand
Ugh. Y does no one explain the explanations, like y u divide it by 2? I already knew how to do this but idk why u divide the 2nd diff by 2
How do you get +1 in 14:42
Cayden C. It’s the nth term for the linear sequence of the difference between the 1/2n^2 sequence and the actual sequence. Watch videos on linear nth term if you’re not sure.
When he says you can use a calculator but you are in year 4:D
You should have talked about
1) why it’s always quadratic if 2nd difference is constant( This comes from differentiation and we can extend it to nth power)
2) why 2nd difference is divided by 2 for co-efficient of n^2(it comes from integration)
Now the differentiation and Integration I mentioned are not in continuous domain but in discrete domain. You can go through “difference equations” to understand calculus in discrete domain.
MrJefferyMaths oh ok . But concept like this should be told why one needs to do this instead of just doing it. Some intuition must be given.
Yo Jeff
Sir the difference btwn -1.5 and -3 is not -1.5.It is actually positive 1.5.
😤
It is far more make sense.
thank you a lot for explain and it is very easy for me
can you give you mailadders for me if i have any dout
Out of all the videos I've watched, this is by far the most helpful for doing it step by step
