100
Halfway between 70 and 100 is (70 + 100) ÷ 2 = 85.
90
176-84=92, and half of 92 is 46.84 + 46 = 130 and 176 - 46 = 130, so 130 is halfway between 84 and 176.
The halfway point between 70 and 80 is (70 + 80) ÷ 2 = 75
130
To find the halfway point between two numbers, you can add the two numbers together and divide by 2. In this case, the halfway point between 50 and 70 would be (50 + 70) / 2 = 120 / 2 = 60. Therefore, 60 is halfway between 50 and 70.
