Answer:
8, 9, 10
Explanation:
x - the smallest integer
3x - three times the smallest integer
x+1 - next consecutive integer (the middle)
x+2 - the largest of three consecutive integers
2(x+2) - twice the largest of consecutive integers
2(x+2)+4 - four more than twice the largest of consecutive integers
3x = 2(x+2)+4
3x = 2x + 4 + 4
-2x -2x
x = 8
x+1 = 9
x+2 = 10
Or if you mean four more than twice the larger next to the smallest:
x - the smallest integer
3x - three times the smallest integer
x+1 - next consecutive integer (the middle)
x+2 - the largest of consecutive integers
2(x+1) - twice the consecutive integer larger than the smallest
2(x+1)+4 - four more than twice the consecutive integer larger than the smallest
3x = 2(x+1)+4
3x = 2x + 2 + 4
-2x -2x
x = 6
x+1 = 7
x+2 = 8
