I think it is the only way to solve this Problem. We Need to get the sides of nth triangle and ist done.

Test	Status	Code Input and Output
1	Pass	n = 1; area_correct = 25; tolerance = 1e-12; assert(abs(triangle_sequence(n)-area_correct)<tolerance) area = 25
2	Pass	n = 2; area_correct = 41; tolerance = 1e-12; assert(abs(triangle_sequence(n)-area_correct)<tolerance) area = 41
3	Pass	n = 3; area_correct = 66; tolerance = 1e-12; assert(abs(triangle_sequence(n)-area_correct)<tolerance) area = 66.0000
4	Pass	n = 50; area_correct = 439116598409; tolerance = 1e-3; assert(abs(triangle_sequence(n)-area_correct)<tolerance) area = 4.3912e+11
