What is the mean of the first 100 integers?

The mean of the first 100 integers can be calculated by finding the sum of these integers and dividing by the total count. The sum of the first 100 integers (from 1 to 100) is ( \frac{100(100 + 1)}{2} = 5050 ). Dividing this by 100 gives a mean of ( \frac{5050}{100} = 50.5 ). Therefore, the mean of the first 100 integers is 50.5.
