In this paper,we firstly modified the mistake in reference of Bennett,then using Strmer s theorem of the solutions of Pell equation,and a deep result of privitive divisor of Bilu,Hanrot and Voutier,we proved that there is no exist four distinct triangular numbers in geometric progression,therefore we sovled the question of Sierpinski on triangular numbers.
