It is 10, the middle value between the two middle numbers.
If you line numbers up, it's the middle number in the group. If you have the numbers 2, 23, and 11, when you line them up in order, they would be 2, 11, and 23. 11 is in the middle, so it would be the median. But, let's say you had the numbers 5, 3, 9, and 6. When you line them up, it would be 3, 5, 6, 9. Five and six are the numbers in the middle. You can't have two medians, so the number would go in between 5 and 6. The median in 5.5 or 5 and a half. Hope I helped!
The numbers are -12, -11, -10 and -9.
No technical reason. Mathematically arranging numbers 1 to 9 in three rows of three just happens to have five in middle of middle row ... 1 2 3 4 5 6 7 8 9
9 and 10 are but 11 is prime
Yes. Both 9 and 11 are prime numbers.
The numbers are increasing by 10, then 9. 1 + 10 = 11, 11 + 9 = 20, and so on.
A paradox occurs in the space-time continuum and the universe ceases to exist ;) But seriously, what you probably REALLY mean is how do you find the median of a list of numbers with an even number of numbers. When you have an even number of numbers, you take the average of the two middle numbers. So for example: 1, 6, 8, 10, 15, 20 The two middle numbers are 8 and 10. The average of 8 and 10 is 9, so the median of the above example is 9.
Take the two numbers in the middle and divide by 2 ( that is the average of those two middle numbers). For example if the two middle numbers are 7 and11 the median is 9
9, 10, 11. Let the middle number be n, then the three numbers are (n-1), n, (n+1) with: (n-1) + n + (n+1) = 30 → 3n = 30 → n = 10 → the numbers are 10-1 = 9, 10 and 10+1 = 11.
The numbers between 8 and 11 are 9 and 10. These numbers fall between 8 and 11 on the number line and are considered consecutive integers. In mathematical terms, they are part of the set {9, 10}.
The multiples of 9 are numbers that can be divided evenly by 9. The two prime numbers closest to a multiple of 9 are 7 and 11. Since 9 is between 7 and 11, the multiple of 9 that is in between these two prime numbers is 9 itself.
