### QUESTION 1 of 10

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
