Could you please tell me what is the formula you use to calculate the end number for growth? For example, I know that something that is 13.8 trillion will grow by 5% each year over next 10 years. What is the result in the 10 years? I am sure this is quite simply done, but I don't know how other than doing the 13.8+5% of 13.8 in year one, etc. which I know is not the right way...(time-wise).
I know how to calculate how much something is growing when I have the starting number and the end and what I need to find out is the growth/decline percentage...
