1st year : A
2nd year : A x 1.035
3rd year : A x 1.035 x 1.035

This forms a geometric sequence with 1st term A and ratio 1.035. What's the nth term of this sequence?

Then which value of n gives 2A?

I don't have time to check your working but you can easily check if your answers work.

Let us know if you think your answers are incorrect or aren't sure.

I checked the markscheme and my answers aren't right. The answers are 1 lower than what I got for n, ie. 11.2 and 20.15

If you are the person in the group chat, then I have already helped you.

But in case not. N is fine. No need to use n-1.
