E is greater than O.

Step-by-step explanation:

We have

O=3+5+7+9 + ... + 105 and E=4+6+8+10 + ... + 106

Number of term in O = (105 - 3) / 2 + 1 = 51 + 1 = 52

Number of term in E = (106 - 4) / 2 + 1 = 51 + 1 = 52

E - O = 1 + 1 + 1 + ... 52 times = 52

So value of E is 52 more than value of O.

E is greater than O.
