    It's a geometric series a + ar + ar^2 + ... with a=1 and r = 3/2. Plug into the formula

    http://en.wikipedia.org/wiki/Geometric_progression if u have finite geometric progession the sum is a1(q^n-1)/(q-1) if u have infinite geometric progresion the formula is a1/(1-r) where where a1 is the first therm r is the common ratio (u multyply all therms in progresion )
