Hello from MrBillDoesMath!
Answer: NO solution possible!
Steps:
Let "n" be the first even number. We are told that
n + (n+2) + (n+4) + (n+6) + (n +8) = 216
The third number, the value we want, is boldfaced above.
Simplify the above equation:
5n + ( 2 + 4 + 6 + 8 ) = 216 or
5n + 20 = 216 or
5n = 196
n = 196/5 is NOT an integer value. This problem, as stated, has no solution.

The simplified expression of (-2 - c)(-1) is 2 + c
<h3>How to simplify the expression?</h3>
We have:
(-2 - c)(-1)
Express as product
(-2 - c) * (-1)
Evaluate the product
2 + c
Hence, the simplified expression of (-2 - c)(-1) is 2 + c

The Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.
<h3>What is Arithmetic mean?</h3>
Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.
Mean = Sum total of the number ÷ n
Where n is number of numbers
Median is the middle number in the data set.
Given the sets;
Mean = Sum total of the number ÷ n
Mean = (2 + 5 + 13 + 15 + 19 + 21) ÷ 6
Mean = 75 ÷ 6
Mean = 12.5
Median is the middle number in the data set.
Median = ( 13 + 15 ) ÷ 2
Median = 14
Therefore, the Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.
