-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
The two square numbers that add up to 100 are 36 and 64. Specifically, 6 squared (6²) equals 36, and 8 squared (8²) equals 64. When combined, 36 + 64 equals 100.
