Adding all integers from 33 to 112 inclusive gives you 5800.
33
They are (33, 34, 35).
They are: 33+34 = 67
18 26 33 19 27 34 20 28 35 ....
The numbers are 32, 33, 34 and 35.
33
-34 and -33
They are (33, 34, 35).
They are: 33+34 = 67
18 26 33 19 27 34 20 28 35 ....
The integers are -34 and -33.
33, 34, 35, 36
The numbers are 32, 33, 34 and 35.
The trick is to add the two numbers together and then divide to sum by two. So in this case 34+33=67. 67 divided by 2 is 33.5
1 x 11 = 112 x 11 = 223 x 11 = 33. ------. 66
316 - 112 -34 = 170
32+33+34=99
