Answer 1

its not C . just took the quiz and it was wrong

                           

Answer 2

The answer would be 1,235,520. To find this you would have to multiply the first six terms following 13.
13!= 13 x 12 x 11 x 10 x 9 x 8

If it wasn't specifically asking for only 6 terms, every number from 13 to 1 would be multiplied.
