on the examples you said series, so i automatically used the second equation, next time plz be more specific
So useful. Thank you (:
why didnt u used the formula of series
on the last question in the video, you didnt need to expand the brackets; you could of just divided both side.
👌👌👌👌
14:27 can I solve for n like this? I5 + 4(n-1) = 805-5. -54(n-1) = 800 // 4n - 1 = 200+1. +1n = 201 ?
This is the same video as the previous one, (4).

I
5 + 4(n-1) = 805
-5. -5
4(n-1) = 800 // 4
n - 1 = 200
+1. +1
n = 201 ?
