3x=x+40(vertically opposite angle)
thus ,
X= 20
Consecutive integers are those that occur one after the other. Let's use 2, 3, 4 as an example.
The middle number is 3 (n). To get to 2 from 3, we need to subtract 1 (n - 1). To get to 4 from 3, we need to add 1 (n + 1).
Now that we understand how to get to each number from the middle number, we can create our expression.
(n - 1) + n + (n + 1)
(n + n + n) + (1 - 1)
3n + 0
Answer: 3n
Hope this helps!
