7 and 21 average provides the comprehensive information about what is the average of 7 and 21, and how it is being calculated mathematically. To calculate the average, the given quantities 7 and 21 can be of any physical quantity but both should have been expressed in the same measurement units.
7 and 21 average:
= (7 + 21)/2,
= 28/2,
= 14
Hence,
the average of 7 and 21 is equal to 14
where,
7 and 21 physical quantities in same measurement units,
28 is the sum of quantities,
2 is the total number of quantities,
14 is the average of 7 and 21
The step-by-step work shows how to find what is the average of 7 and 21. The solution for 7 and 21 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 7 and 21?
step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 7
Quantity B = 21
What to be found:
Find the average of 7 and 21
step 2 Find the sum of quantities 7 and 21.
7 + 21 = 28
step 3 Find how many number of inputs:
The calculation involves two quantities 7 and 21, so the number of quantities is 2.
step 4 To find the average of 7 and 21, divide the sum of quantities 28 by the total number of quantities 2:
= 28/2
= 14
(7 + 21)/2 = 14
Hence,
14 is the average of 7 and 21.
