Answer:
v - w - 1
Step-by-step explanation:
Try an experiment with a small, specific set of numbers like:
4, 5, 6, 7, 8, 9, 10 w = 4 and v = 10.
There are 5 numbers in the list, not counting the first and last. Is this related to the difference between v and w? v - w = 6, one more than 5.
The number of natural numbers between w and v, not including w and v, is v - w - 1.
255 is the answer because 143+86=229, 229+23 is 255
Are there any answer choice?
So the ratio is 40/26 = 1.54
24 ÷ 1.54 = 15.58
2x-4 = 15.58
2x = 19.58
x = 9.8
