Answer:

  -4, -2, 2, 8

Step-by-step explanation:

The first four terms will be found by evaluating the expression for values of n that are 1, 2, 3, 4. Evaluating for n=1 is sufficient to determine the correct answer choice:

  n(n -1) -4

  1(1 -1) -4 = -4 . . . . matches the third choice

Answer:

10 customers.

Step-by-step explanation:

1/12 pounds of pasta = 1 customer

1 pound of pasta = 12 customers

Therefore, 5/6 pounds of pasta = 5/6 x 12

                                                     = 5 x 2

                                                     = 10 customers
