The value of the middle number amongst the three numbers in discuss is; x = -22.
<h3>What is the value of the middle number according to the task content?</h3>
It follows that one can assume the middle number in discuss to be; x.
On this note, the sum can be written as follows;
(x-1) + x + (x+1) = -66
3x = -66
x = -22
Ultimately, the value of the middle number amongst the three numbers in discuss is; x = -22.

Answer:
Length = 19m
Width = 8m
Step-by-step explanation:
Let the width be x meters
The length will be 2x + 3 meters
The perimeter is 56m
Perimeter is given by 2(length) + 2(width)
2(2x + 3) + 2x = 56m
4x + 6 + 2x = 56m
6x + 6 = 56m
6x = 56 - 6 = 50m
x = 50/6m
Simplifying gives;
x = 8m
Length = 2x + 3 that gives;
2(50/6) + 3 = 50/3 + 3
Working out further gives;
Length = 19m
