Write them in a column. Since there is only one number per row, there is no chance of consecutive numbers being in the same row.
Any three consecutive integers are divisible by three because it can be shown that the sum divided by three is the middle number.

4! = 4 * 3 * 2 * 1 = 24 ways[1]
246 and 248.Any even number can be written in the form 2n, for some integer n. The next consecutive integer is 2n + 2. These two numbers added together equal 494:2n + (2n + 2) = 494so4n + 2 = 4944n = 492n = 123so2n = 246 and 2n +2 = 248.
Rational and irrational numbers are part of the set of real numbers. There are an infinite number of rational numbers and an infinite number of irrational numbers. But rational numbers are countable infinite, while irrational are uncountable. You can search for these terms for more information. Basically, countable means that you could arrange them in such a way as to count each and every one (though you'd never count them all since there is an infinite number of them). I guess another similarity is: the set of rational numbers is closed for addition and subtraction; the set of irrational numbers is closed for addition and subtraction.
This is impossible to achieve with integers. If the numbers are consecutive even numbers, then this is the solution: 42 + 62 = 16 + 36 = 52

Arrange the numbers from smallest to largest and find the middle number.
When you are given some numbers just arrange them in ascending order and you will the smallest number which can be made out of those given numbers.
Arrange the numbers least to greatest. The median is the number in the middle if you have an odd number of numbers. It's the average of the middle two if you have an even number of numbers.
The idea here is to use the formula for the sum of an arithmetic series. In this case, the starting number is of course 1; the interval is 2.
6 and 8
Arrange the numbers in ascending order, and then take the mean of the fourth and fifth number.
four consecutive odd, whole numbers cannot have an average of 549. four odd numbers added together would be an even number. an even number divided by another even number (in this case, four) will only yield an even number.
