How do you quickly find the average of a series of evenly spaced numbers?
For evenly spaced numbers, the average is the middle value. To find the average of evenly spaced numbers, just average the smallest and the largest.For example, the average of all the integers from 13 through 77 is the same as the average of 13 and 77.13 + 77/ 2 = 90/ 2 = 45
To quickly find the average of a series of evenly spaced numbers, you can use the arithmetic mean formula, which is (first term + last term)/2.
For example, let’s say we have a series of evenly spaced numbers: 2, 4, 6, 8, 10.
To find the average of these numbers, we can use the arithmetic mean formula:
(2 + 10)/2 = 6
Therefore, the average of the series is 6.
Another way to find the average of a series of evenly spaced numbers is to simply add up all the numbers and divide by the total number of terms.
Continuing with our example of 2, 4, 6, 8, 10:
2 + 4 + 6 + 8 + 10 = 30
Since there are five numbers in the series, we divide by 5:
30/5 = 6
Again, we get an average of 6.
Either way, the process is quick and straightforward.
