اسلوب وطريقه ممتازه لفهم كيفية استنتاج الحد العام لمتسلسلة اعداد وانصح بتحميله وكذلك استنتاج الحد العام للمتتابعه الخطيه والتربيعيه بنفس هذا الاسلوب البسيط

[@FarhanKhan-hc1if]

is there a shorter way?

[@amalldekan1432]

no

[@lidetten]

Only shorter way is if you actually remember the mini formulas... for every cubic seq you will always find that
a = 1/6 of the 3rd difference,
12a+2b= to the first of the 2nd difference
7a+3b+c= to the first of the 1st difference
a+b+c+d=to the first term.
That is a lot to remember though

6:28 how did you get 6a=1?

[@vivekpanchagnula815]

he didn't, he got 6a = 6. thus (dividing by 6 both sides) a = 1

[@RandomEmperor]

U should improve he writing thing to make it easier
Lol
I didn't dislike
