This paper researches the problems of triangular numbers in two recurrent sequences {Vn} and {Un} which are given by the units Vn+Un(7~(1/2))=(8+3(7~(1/2)))n of quadratic field Q(7~(1/2))
and finds out all triangular numbers in {Vn} and {Un}.As applications
all integer solutions of two related Diophantine equations are obtained.
