Answer 1

Answer:

5

Step-by-step explanation:

First five odd numbers are :

  1  , 3 ,  5  , 7 , 9

We know,

     Average = sum of quantities / number of quantities

Here,

 Sum of quantities = sum of first 5 odd number = 1 + 3 + 5 + 7 + 9 = 25

Number of quantities = 5

 Therefore,

Average = 25 / 5

      = 5
