# Continuous compound formula...Differention question watch

1. Hello guys,

I am stuck on a problem, so I hope to be able to pick some brains about it.

How do I use the Continuous compound interest formula to find the balance on an account that already has an initial investment (say..100 pounds for example) with money periodically deposited into the account after X amount of years? with interest and deposits being made on an annual basis?

All help appreciated!
