There are several ways to find the number exactly **halfway** between two given numbers.

We shall use two easy numbers, such as 60 and 70, to illustrate three different methods.

**Method 1**

Find the difference between the two numbers, which here is 70 - 60 = 10

Halve this difference, which here is 10 ÷ 2 = 5

Add this to the smaller number, which here is 60 + 5 = **65**

**Method 2**

Find the difference between the two numbers, which here is 70 - 60 = 10

Halve this difference, which here is 10 ÷ 2 = 5

Subtract this from the larger number, which here is 70 - 5 = **65**

**Method 3**

Find the mean of the two numbers by adding them together and halving the result.

The total is 60 + 70 = 130

Halve the result to get 130 ÷ 2 = **65**

In this activity, you can use whichever method you prefer!
