There is no way to measure this. However, if it was multiple choice with four possible answers, and one was correct, then you would have a 25% chance of getting it right.

The sum of three consecutive is 267. What is the largest integer
Oliga [24]
Consecutive means in order. So let's call the first integer x. The next number in line would be x+1 and the largest integer would be x+2. Let's prove that so you're not confused.  If x is 3, then x+1 is 4 (next in line), and x+2 is 5 next after that. See? So if we add all those together we set them equal to 267 and solve for x: x + x+1 + x+2 = 267.  Combining like terms gives us 3x + 3 = 267 and 3x = 264. Now dividing both sides by 3 we get that x = 88.  That's the smallest integer; the largest is found by adding 88 + 2 which is 90.  So that means that the numbers are 88, 89, 90, and that adding them up = 267. Let's check that now: 88+89+90=267 so we're good.
