Find three consecutive even integers such that the sum of the first and third exceeds one-half the second by 15.
-------------
1st even: 2x
2nd even: 2x+2
3rd even: 2x+4
-------------------
EQUATION:
2x + (2x+4) = (1/2)(2x+2) + 15
4x+4 = x+1 + 15
3x = 12
x = 4
----------
1st even: 8
2nd even: 10
3rd even: 12
==================
