Oh, dude, halfway between 1.5 and 1.6 on a number line is 1.55. It's like right smack dab in the middle there, you know? So, if you were walking from 1.5 to 1.6, you'd stop at 1.55 for a quick breather before continuing on your journey.
It is 15.5, the value halfway between the two middle numbers.

Well, honey, the number halfway between 16 and 90 is 53. Technically correct, but let's be real, you could have figured that out with a calculator faster than it took you to ask me. Now go on and enjoy that middle-of-the-road number like the math whiz you are.
The halfway point between two numbers is calculated by finding the average of the two numbers. In this case, the average of 6.5 and 9.5 is (6.5 + 9.5) / 2 = 16 / 2 = 8. Therefore, halfway between 6.5 and 9.5 is 8.
