The answer depends on what number is missing and what numbers are known!

Yes.

With only one number, you cannot - unless that one number happens to be the measure of the missing angle!

you find out missing numbers in addition by subtracting the numbers that are writen

The median is the middle number. If there is an odd number of numbers in the set, the median is the middle number, and the only way to find the missing number is if the median is the missing number. If there is an even number of numbers in the set, the median is the average of the two middle numbers, and the only way to find the missing number is if the median is one of those two numbers. If it is, you can take the median and the one of the two numbers you know. Use the formula (# +#)/2=median and solve.

You cannot.

You cannot.

there is not one

Add all the numbers and divide it by however many numbers you added, then that's how you get the missing number to help you complete the mean.

If there is no mean it is very rare that you will be able to find a missing number. Potentially if you have other numbers and you have a mode you can deduce the missing number by using the mode (if there needs to be one more of a certain number or a certain number cannot be increased in its count of numbers i.e. you can't have more 6's to maintain the current mode).

the missing number is netween the 21 and the 24. what is it ?

The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.

Missing....? But the answer to find the missing is normally either "algebra" or "find another equation to use."

In an addition sum, if the missing number is the first number, for example, x + 5 = 10, then to find x, perform the sum 10 - 5, producing the solution x = 5. In a subtraction sum, if the missing number is the second number, for example, 7 - y = 4, then to find y, perform the sum 7 - 4 = 3, production the solution y = 3.

It can be an extremely difficult process and that is why factorisation is at the root of cryptography.
