Annual interest rate from different monthly interest rates

Let's says I have unequal monthly interest rates (1,5% in the first month, 1,7% in the second, -0,8% in the third...) is there a way I can calculate what was my interest rate in the semester or in the year? On all the formulas I could manage to find it is taken into consideration that monthly rates are always the same.
