Question 569401
The middle number of seven consecutive even numbers is 1004. What is the first number?
----
Let the middle even number be 2x:
2x = 1004
1st previous 2x-2 = 1002
2nd previous 2x-4 = 1000
3rd previous 2x-6 =  998
---------------------------------------------------------------
Ans: 998
