A new pseudoperturbative (artificial in nature) methodical proposal  is used to solve for Schrödinger equation with a class of phenomenologically useful and methodically challenging anharmonic oscillator potentials . The effect of the [4,5] Padé approximant on the leading eigenenergy term is studied. Comparison with results from numerical (exact) and several eligible (approximation) methods is made.
