G'day all,

does anyone know a formula which allows you to calculate a value in a 
geometric progression. For example if a number doubles 2.8 times in 10 
years, what will that number be. At the moment the only way I can do it is 
"long hand" ie if 10 is going to double 2.8 times then it would be 10 
doubled to 20, twenty doubled to 40 then add 80% of the next double ie 32 
plus the 40 equals 72, BUT is there a formula, so I can put in other times 
of doubling. 

Troubled
