Question

With out computing each sum find which is greater O or E and how much O=5+7+9+11...+101

E=4+6+8+10....+100

Answer 1

O is greater.

Greater by 49.

Explanation:

O is greater because it has the same number of terms as E but taking term by term O's terms are 1 greater than E.

Each series has 49 terms:

(101 - 5) / 2 + 1 = 49 terms

and (100- 4) / 2 + 1 = 49 terms.

So series O has a sum 49 greater than E.
