Get all middle values between 2 numbers

I want to get a middle value from 2 numbers, lets say the first number I have is >3 and the second number I have is <3 so 3 is a middle value here, and for instance I say first number is >5 and a second number is <3 so 3,4 & 5 should be the result. What is the suitable method for finding these values?

When using C or C++ you have to be careful because signed integer overflow is undefined. Starting with c++20 you can use std::midpoint to avoid all kinds of pitfalls.

You can add both values and then divide them by 2. If you don't get an integer you can round up or down. If you give a language, you can get a snippet, but here is Java anyway:

int a = 2;
int b = 4;
int middleValue = Math.round((a+b)/2);

EDIT After more details are added, the Java solution would look like this:

int start = 2;
int end = 6;
List<Integer> middleValues= new ArrayList<Integer>();

for(int i =start+1; i <= end; i++){
     middleValues.add(i);
}

Then your middleValues contain what you need.

If you are not dealing with integers, you can also use: Math.floor(start) and Math.ceil(end) in your loop conditions.

To find the best middle value ( Average ) you can follow the next formula:

(x + y) / 2

in your example

(3 + 3) / 2
