Answer:
Step-by-step explanation:
Four consecutive counting numbers would look like this
x
x + 1
x + 2
x + 3
Do you see that these numbers are 1 larger than the one before it. So if x is 20 the numbers would be 20 21 22 23
Now take the 4 general numbers and add them
x + x + 1 + x+2 + x + 3
4x + 6
Two will go into 4x to give 4x/2 = 2x
Two will go into 6 to give 6/2 = 3
Always happens. There are no exceptions. Try x = 20 again
20 + 21 + 22 + 23 = 86
Can this number be divided by 2? Yes it can 86/2 = 43
