-20a-28 I believe is the answer!
You first distribute 7 into -2a-4, which gets -6a-14a-28. You then combine like terms -6a and -14a, to get -20a-28 which you cannot combine anymore!
Hopefully that’s correct :3

The sum of 5 consecutive even numbers is 216. What is the third number in the sequence
alexandr1967 [171]

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.

Regards, MrB
