31+32+33 = 96
There is no set of three consecutive odd or even integers whose sum is negative 31.
16 and 17
-1, 1 and 3
The sum of three consecutive integers can be expressed using ( l ) as the middle integer. The three integers can be represented as ( (l-1) ), ( l ), and ( (l+1) ). Therefore, the sum is ( (l-1) + l + (l+1) = 3l ).
The integers are 53, 55 and 57.
The sum of three consecutive integers is -72
There is no set of three consecutive odd or even integers whose sum is negative 31.
51
50
16 and 17
The sum is 3*(x-1) or 3x - 3
156 and 158 sum to 314.
-1, 1 and 3
The integers are 53, 55 and 57.
0.75*(2n+1) where n is an integer.
Their sum is three times the middle number.
231 / 3 = 77So 76 + 77 +78 = 23177
