Determine amount of sales 5 years in the future for a stock?

Question

Known Facts :
Sales For 1st year = 7230
Sales for 10th year =32259
Above numbers are in Mil
Historical growth rate for above period was 0.18077
by using formula
((32259/7230)^(1/9))-1=0.18077

Question is finding sales value 5 years in future?

I estimate it is around 54000!

I think formula would be close but I do not know how to find XX?

((XX/32259)^(1/4))-1 = 0.18077739

I used 4 for years as that was number of year from the end of the 10th year to the end of the 15th year.

Thanks for your help!

Answer 1

You need a crystal ball that isn't cracked.

Answer 2

XX = (0.18077739 + 1)^(4)*32259
= 62708.1
