It is: 45
Halfway between 30 and 80 is (30 + 80) ÷ 2 = 55.
The number halfway between two numbers is the average of those two numbers. In this case, the average of 30 and 60 is (30 + 60) / 2 = 45. So, the number halfway between 30 and 60 is 45.
25
Halfway between 15 and 30 is the average of the two numbers. To find the average, you add the two numbers together and then divide by 2. In this case, (15 + 30) / 2 = 45 / 2 = 22.5. Therefore, 22.5 is halfway between 15 and 30.
It is 25
65
42 is exactly halfway between 32 and 52.42
Halfway between 30 and 80 is (30 + 80) ÷ 2 = 55.
The number halfway between two numbers is the average of those two numbers. In this case, the average of 30 and 60 is (30 + 60) / 2 = 45. So, the number halfway between 30 and 60 is 45.
The number 30, itself, is a decimal number. So it is the nearest.There is no other "nearest" number. If there were, the number halfway between that number and 30 would be nearer to 30. And then the number halfway between that number and 30 would be nearer still. And so on.

It is: 48
The number between 1 and 30 could be any integer in that range, such as 15, which is exactly halfway between the two. However, without further context or a specific criterion, it's impossible to pinpoint just one number in that range.
30
It is exactly halfway between the tick marks that are labelled 20 and 30.
