4 / -16 = -1/4. (also -1/4 = -1/4).

The general form of the sequence is:
a, ar, ar^2, ar^3....

Where r is the ratio: 1/4, and a is first term: -16.

You can see each term is just ar^n where n is the term number, starting where the first term n=0.

So the general formula would be:

-16(-1/4)^n

jocelyn bought 2 sweaters for the same price. she paid 23.56,including sales tax of 1.36 and a 5.00 discount coupon. what was th
wel
Number of sweaters bought by Jocelyn = 2
Price of the 2 sweaters including tax and discount coupon = 23.56
Amount of ales tax taken = 1.36
Amount of discount coupon = 5.00
Then
Price of 2 sweaters before tax = 23.56 - 1.36
                                                 = 22.20
Then
Price of the sweater before discount coupon was applied = 22.20 + 5.00
                                                                                             = 27.20
So
Price of 1 sweater before tax and coupon discount = 27.2/2
                                                                                   = 13.6
So the price of 1 sweater before tax and coupon discount is 13.6.
