Answer 2

To find: average of given numbers

Given data : $3,5, 7$

Solution :

• Average is the arithmetic mean .

• It is the ratio of sum of all the numbers given in data to the total number of observations .
• Formula :  $Average = \frac{sum\ of \ all \ the \ observations}{total \number \ of\ observations }$
• Here , sum of observations  = $15$
•           Total number of observations = $3$
• Substituting values in above formula ,

                $Average = \frac{15 }{3}$

                              $=5$  

Hence , average of given data is $5$ .
