21 and 38 average provides the comprehensive information about what is the average of 21 and 38, and how it is being calculated mathematically. To calculate the average, the given quantities 21 and 38 can be of any physical quantity but both should have been expressed in the same measurement units.
21 and 38 average:
= (21 + 38)/2,
= 59/2,
= 29.5
Hence,
the average of 21 and 38 is equal to 29.5
where,
21 and 38 physical quantities in same measurement units,
59 is the sum of quantities,
2 is the total number of quantities,
29.5 is the average of 21 and 38
The step-by-step work shows how to find what is the average of 21 and 38. The solution for 21 and 38 average is same for all the following queries but have to append the measurement units based on the measurement units of physical quantities being measured.

Solved Example:
what is the average of 21 and 38?
step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 21
Quantity B = 38
What to be found:
Find the average of 21 and 38
step 2 Find the sum of quantities 21 and 38.
21 + 38 = 59
step 3 Find how many number of inputs:
The calculation involves two quantities 21 and 38, so the number of quantities is 2.
step 4 To find the average of 21 and 38, divide the sum of quantities 59 by the total number of quantities 2:
= 59/2
= 29.5
(21 + 38)/2 = 29.5
Hence,
29.5 is the average of 21 and 38.
