    my teach taught this to me in year 9. i was top set, and pretty lazy, so my attention span those lessons was... lackiing. Ever since, its been coming up in tests. end of topics, end of years, and i've just been crawling along, no sense of direction with the method. Of the many tutorials that i've found, this one clicked. Thanks!!!

    Reading the comments, I see a few people getting confused on the last question where we "+1" so allow me to elaborate.
    The reason the last part is "-2n+1", and not "-2n-1". The "+1" , allow me to explain:
    -1, -3, -5, -7, -9
    We evaluate our sequence and observe how it's moving. The sequence is moving in the negative times 2 pattern so:
    -2, -4, -6, -8, -10
    Now lets write them both together,
    -1, -3, -5, -7, -9

    I am in grade 7. I am going for the InIMC (India International Mathematics Competition) in 5 days. On the test deciding which 8 students are going, the first question had something about quadratic sequences. I didn't know what they were at the time, and got it wrong. I thought it was impossible, after watching this, I realise how UNBELIEVABLY EASY it was. Thank you so much for this amazing tutorial, you earned a subscriber. I genuinely love you for helping me so much. ❤❤❤
