3050.
Halfway between them is 3150.
% increase = 100*(3100/3000 - 1) = 3.33..%

2,500 is halfway between 2000 and 3000
3000 + 100 = 3100

3000 and not 2900
550/3000 = .18333... if we were to try to make this into a simpler kind of fraction, we could say that it is about halfway between a fifth and a sixth.
The number that is in between 2000 and 3000 is 2500. This number falls exactly halfway between the two given numbers on the number line. It can be calculated by finding the average of the two endpoints: (2000 + 3000) / 2 = 2500.
It is: 4000 --------------------------- 5000 - 3000 = 2000 and 2000/2 = 1000, so 3000+1000 = 4000 and 5000-1000 = 4000 The easiest way to find the halfway point (the average): add the two numbers and divide by 2.
