Finding Terms of Sequence involving factorials and evaluating fractions with factorials.
Factorial Notation is often used in questions in combinations. Needed when multiplying consecutive numbers.
Factorial Notation is simple 7!---> 7x6x5x4x3x2x1= 5040 // To find terms of sequence, you must begin with the first FOUR terms. (1,2,3,4) . // Evauluating fractions is simple as well, the same as factorial notation just with fractions.
