Question 204066
Here are your 4 consecutive even integers:

x
x + 2
x + 4
x + 6

=========================================
We now add them and equate the whole thing to 340. Then we solve for x.
By the way, you can use letter.  I always use x, y or z because they are popular letters in algebra.

x + x + 2 + x + 4 + x + 6 = 340

4x + 12 = 340

4x = 340 - 12

4x = 328

x = 328/4

x = 82

=========================================

Now that we know x, we plug that value of x into the 4 consecutive numbers given above and simplify (where needed).

Here are the 4 numbers:

82, 84, 86, 88
