We investigate inflation in closed Friedmann-Robertson-Walker universe filled with the scalar field with power-law potential. For a wide range of powers and parameters of the potential we numerically calculated the slow-roll parameters and scalar spectral index at the epoch when present Hubble scale leaves the horizon and at the end of inflation. Also we compare results of our numerical calculations with recent observation data. This allows us to set a constraint on the power of the potential: alpha < (3.5 - 4.5).
