Answer:
1.5
Step-by-step explanation:
Think of a number line, on the number line are the points 1 and 2, the number between those points is the midpoint.
You can also average 1 and 2 to get the midpoint. To average any number sequence, simply add all of the numbers and then divide the sum of those numbers by the amount of numbers there are.
In this case add 1 and 2 to get 3 then divide 3 by 2 (because there are two numbers) to get 1.5
