The sum of 3 consecutive integral numbers is 117. find the numbers.

An integral number is just a whole number. Consecutive means they are neighbouring in the number line (e. g. 2,3,4). Let the smallest number be x:

x + (x+1) + (x+2) = 3x + 3 = 117

3x = 114

x = 38

Hence the numbers are 38, 39, 40
