Answer 10

So you found half of the distance between 2 and 6.5.
Good 2.25.

We started at 2 though.
So you need to add 2.25 to your 2 to find the half-way point.

Answer 11

oh*

Answer 12

4.25

Answer 13

2.25 is clearly not the half-way point lol

Answer 14

yay good job \c:/

Answer 15

yeah lol!

Answer 16

so its 4.25?

Answer 17

An alternative is to add up the two numbers. Then divide by 2


\[\Large \frac{2+6.5}{2}=\frac{8.5}{2} = 4.25\]


and you get the same answer. The method zepdrix used is probably more intuitive though.
