For question number 1, let the numbers be: x, x+2, x+4. So the formula would be: 120 = (x) + (x+2) + (x+4). The answer would be: x=38. So the integers are: 38,40, and 42. 

For question number 2, let the numbers be x, x+1, x+2. So the formula would be: (x) + (x+2) = (x+1) + 21. The answer would be x=20. So the integers are 20, 21, and 22.

For question number 3, let the numbers be x, x+2, x+4, x+6. So the formula would be: 4(x + x + 2) = 8 - 7(x+6). The answer would be x=26. So the integers are 26, 28, 30, and 32.
