Tell whether the sequence is arithmetic. if it is, what is the common difference? 19, 12, 5, -2

The common difference in the arithmetic sequence is -7.

Given that,

Sequence; 19, 12, 5, -2

The sequence is arithmetic.

We have to determine,

The common difference of the sequence.

According to the question,

The common difference in the arithmetic progression is given by the following formula;

Common difference = second term - first term

Then,

The common difference between the terms is,

Common difference between first and second term =  12 - 19 = -7

Common difference between second and third term =  5 - 12 = -7

Common difference between third and fourth term =  (-2) - 5 = -7

Therefore, The common difference in the arithmetic sequence is -7.

The sequence is arithmetic.  The sequence is decreasing 7 each time so the common difference is -7

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
