5050, ie (1 + 100) x (100/2)
-99
-99
The odd numbers 1-99 will be a higher total than the even numbers 2-98
You can either just add them up or use quick logic to add them in pairs: All the numbers from 1 to 49 match up with 51 through 99 to = 49 pairs of 100 = 4900, than add the two you skipped 4900 + 50 + 100 = 5050 total
