      wouldn't starting with 4 and 6 as the two consecutive even number be more correct for the very last question? my answer was 8(n^2+3n+2)+4

    omg thank you so much for this video. Algebraic proof has been one of the topics in maths that i have always hated because i never understood how to do it but this video actually made me realise how simple it is (like most things in gcse maths) once you get the hang of it. THANK YOU!! Good luck to anyone else doing exams this year!

      Aaryan Ramani That entirely depends on your comfortability working with negatives, I would say it’s the same difficulty but some students may find it more difficult as you have the be more aware of using negative numbers.
