The sum of five consecutive even integers is 20. What is the product

The numbers are 0,2,4,6,8.
Median is 4.
Smallest integer is 0.
So product is 4*0=0.
So E is my answer.

Sent from my Lenovo TAB S8-50LC using GMAT Club Forum mobile app

x + (x+2) + (x+4) + (x+6) + (x+8) = 20

5x + 20 = 20
5x = 0

x = 0 = smallest term
Median is x + 4 = 4
Product: 4*0 = 0

Answer E

Bunuel - I've asked the question below a couple of times. So far no response.

If at all, when \(must\) we assign "2x" for consecutive even integers, and (2x + 1) for consecutive odd integers, as opposed to using just "x" for both?

I've seen different approaches.

Some mathematicians always use "x" to denote the first term, whether the sequence is consecutive evens, or consecutive odds.

Others always use 2x for consecutive even integers, and (2x + 1) for consecutive odd integers. I understand that these latter two formulations guarantee even and odd integers, respectively.

That said, I have only seen one problem where using simply "x" made a difference in the accuracy of the answer, and it seemed strange.

So does the difference in variable assignment matter? Obviously, the simple "x" (instead of 2x) for consecutive even integers worked here.
