0 + 100 = 100
1 + 99 = 100
2 + 98 = 100
...
49 + 51 = 100
so 50 x 100 + 50(the middle number not paired up) = 5,050
this technique will work for any group of consecutive numbers
if even then total = (N/2) x (N+1)
if odd then total = (N/2 round up) x N
if you had the question: add all numbers from 624 to 1234
find total for 1234 and subtract the total for 623
1234 total = (1234/2) x (1234+1) = 617 x 1235 = 761995
623 total = (623/2 round up) x 623 = 312 x 623 = 194376
final answer = 761995 - 194376 = 567619
