Simply calculate the average of the two numbers.
Halfway between 18 and 28 is (18 + 28) ÷ 2 = 23.
55
28
To find the number halfway between any two numbers x and y, add x and y, then divide the answer by 2. So for 21 and 35, 21+ 35 = 56. 56/2 = 28. You can check your answer by seeing that 21 + 7 = 28 and 35 - 7 = 28.
two and seventy five hundredths
It is: 28It is: (14+42)/2 = 28
-11 = (-50+28)/2 -11 is the answer you seek. It is 39 integers from -50 and 28. (i.e. it is in the middle)
It is: (28+82)/2 = 55(28 + 82)/2 = 55
28
27 41 - 13 = 28 Half is 28/2 = 14 13 + 14 = 27 = 41 - 14
It is 32, the number halfway between the two middle numbers, when they are arranged in order.
It is 30, the number halfway between the two middle numbers.
