-the amount on your savings account ;
-the amount of money in your piggy bank if you deposit the same amount each week (a bank account with regular deposits leads you to arithmetico-geometric sequences) ;
-the size of a population in exponential growth, e.g. bacteria in a Petri dish (or in your leftovers if you find Petri dishes not "every day life" enough) ;
-the intensity of radioactivity after n years of a given radioactive material (with application to determining the age of mommies!).
