23

25

26

28

Answer 1

The trick here is to represent the 3 integers algebraically.
What does "consecutive" mean? Example of 4 consecutive integers: -1, 0, 1, 2
Represent the first integer (not yet known) by x.
The next consec. int. is 1 greater: x+1.
Would you please represent the next one.
Then, add together these three representations. Equate the sum to 72. Solve for x.

Then, list the 3 consec. ints. List x first, then x+1, then x+2.
