173, excluding the two end-points.
The sum is 75.
The sum of -5 and 20 is 15. The distance between -5 and 20 is 25. The sum of the numbers between -5 and 20 is 180. The sum of the numbers from -5 to 20 is 195.
To find the sum of all prime numbers between 20 and 40, we first list out the prime numbers in that range: 23, 29, 31, 37. Then, we simply add them together: 23 + 29 + 31 + 37 = 120. Therefore, the sum of all prime numbers between 20 and 40 is 120.
23+29 = 52
The sum of all even numbers between 10 and 20 can be found by adding the even numbers in that range. The even numbers between 10 and 20 are 12, 14, 16, and 18. Adding these numbers together, 12 + 14 + 16 + 18 equals 60. Therefore, the sum of all even numbers between 10 and 20 is 60.
To find the sum of all even numbers between 10 and 20, we first need to identify the even numbers in that range. The even numbers between 10 and 20 are 10, 12, 14, 16, and 18. Adding these numbers together, we get 10 + 12 + 14 + 16 + 18 = 70. Therefore, the sum of all even numbers between 10 and 20 is 70.

The prime numbers between 4 and 20 are 5, 7, 11, 13, 17 and 19. Their sum is 72.
The sum of two numbers between 20-40 is 58. The difference is 12
173, excluding the two end-points.
Something like this: sum = 0 for i = 2 to 20 step 2 { sum = sum + i }
You need at least two numbers to find something in common between them.
