A new pseudoperturbative (artificial in nature) methodical
proposal [15] 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.
