18:07 The answer should be 3825 i think it's 5050-1225.

The one thing he said you didn't need to know is the only reason I clicked on the video lol, the sum up to infinity came up on my practice past paper

18:00 you made a mistake. Final answer should be 5050 - 1225, not just 1225

Hello, it would be helpful if anyone can help me understand why he chose k-2 to be take away.

Dear teacher, Thank you for posting those useful videos. I have 2 questions here, please help.

1. You write r=1 under the sigma notation? However, I saw a book write it as n=1. What's
difference?
2. At example one, question 2, (at 2:30 in the video) it says 12 above the sigma notation?
There are 6 terms (from 7, 8, 9, 10, 11, 12), therefore, should it be 12 or 6?

Regards,
