Ah, what a happy little question we have here! To find the number halfway between 7 and 15, we simply add them together and divide by 2. So, 7 + 15 is 22, and half of 22 is 11. There you go, a beautiful number right in the middle, just like a peaceful stream flowing through a meadow.
Well, darling, if you can't figure out that 11 is the number smack dab in the middle of 7 and 15, then I don't know what to tell you. It's not rocket science, honey, just basic math. So, there you have it, 11 is the magic number you're looking for.
The number halfway between two values is the average of those values. In this case, the average of 7 and 15 is (7 + 15) / 2 = 22 / 2 = 11. Therefore, the number halfway between 7 and 15 is 11.
7.5
Then number half way between them is their mean average: (-3/7 + -15/14) ÷ 2 = (-6/14 + -15/14) ÷ 2 = -21/14 ÷ 2= -21/28 = -3/4
The number halfway between 4 and 7 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, (4 + 7) / 2 = 11 / 2 = 5.5. Therefore, 5.5 is the number halfway between 4 and 7.
The answer is 1414
It is 20, the number halfway between the two middle values.
