5 and 18 Average

5 and 18 average provides the comprehensive information about what is the average of 5 and 18, and how it is being calculated mathematically. To calculate the average, the given quantities 5 and 18 can be of any physical quantity but both should have been expressed in the same measurement units.

5 and 18 average:
= (5 + 18)/2,
= 23/2,
= 11.5

Hence,
the average of 5 and 18 is equal to 11.5

where,
5 and 18 physical quantities in same measurement units,
23 is the sum of quantities,
2 is the total number of quantities,
11.5 is the average of 5 and 18

The step-by-step work shows how to find what is the average of 5 and 18. The solution for 5 and 18 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 5 and 18?

step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 5
Quantity B = 18

What to be found:
Find the average of 5 and 18

step 2 Find the sum of quantities 5 and 18.
5 + 18 = 23

step 3 Find how many number of inputs:
The calculation involves two quantities 5 and 18, so the number of quantities is 2.

step 4 To find the average of 5 and 18, divide the sum of quantities 23 by the total number of quantities 2:
= 23/2
= 11.5
(5 + 18)/2 = 11.5

Hence,
11.5 is the average of 5 and 18.
