I am confused with the part at 3:40 , why do we add another x? In the video about compound interest (INTEREST: Simple Interest vs Compound Interest), this wasn't the case. I am sure there is some difference here but I am not catching it.

Hey there, I just wanted to know which video you meant when saying that you will leave a video linked somewhere to explain why the Geo-series has a formula like this 5:50

The annual return of sp500 is not counting dividends...with dividends its around 10%...

[@swagatochatterjee7104]

I guess we should also divide the (1+r) with (1+i) (where i is the inflation rate) in the equation and then find the closed-form solution of the geometric series just to be safe!

[@DrTrefor]

Yup this is all ignoring inflation. There are actually a couple ways to deal with it, going to be subject of an upcoming vid

@Drtrefor, please help out with problem, i have spent alot of time to get formula or answer - A has retired with corpus of 1.5 Crores & he can invest at 7% pa.

[@aminnima6145]

Why do i love u

[@jfbjavaforbeginners4176]

yep I was the first to comment doctor

[@DrTrefor]

Congrats! I think that is your first "first"!

[@christopherwalsh3101]

the market itself is going through exponential growth, and the annual return of Sp500 and QQQ, have been much better that 6% a year.

[@DrTrefor]

Last year has been crazy! It is only down at a number like that when considering very long term historical numbers.
