Question 1163462
<br>
Remove 4 from E and you have<br>
O = 5+7+9+...+97+99
E = 6+8+10+...+98+100<br>
In those two sums, the numbers of terms are the same, and each term of E is 1 more than the corresponding term of O.<br>
So even without the term 4 in the given definition of E, E is greater than O.  So certainly with the additional term 4 in E, E is greater than O.<br>
