Hi, thank you so much for the really helpful videos. At 16:52 i dont undedrstand why n=26, i understand that technically there are 26 terms but i thought only 25 years are getting the interest? Thanks again for the videos.
This question was tough, in particular the reading of it. There are 25 subsequent years (after the first year) so 26 years in total, all of which get interest. The increase only happens from year 2 onwards, but this of this as each year is increased on the previous year, which is why we still use 26. I hope this makes sense!
At 17:33 For some reason i am not able to come up with the correct end sum with my calculator, no matter how many times i put it in, or rearrange ur or even dissect it, i don’t get the same answer. I keep making these type of mistakes but i don’t know what I’m doing wrong.
I have just double checked and it is the correct answer... It is hard to help when I can't see what exactly you are typing, but make sure you type it in exactly as it is written. It is easy to drop a 0 when working with decimal or even leaving out a bracket can make a difference! When you are working ensure you write down the sum and then even if something goes wrong when putting it into the calculator, you will have maximised your marks.
Such a useful video! Please never delete these!!
Thank you! I am glad it was useful!
