Question

find the average of odd number up to 15​

Answer 1

Step-by-step explanation:

Odd no's from 1 to 15:

1,3,5,7,9,11,13,15 = 8.

⇒ Avg = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15.

------------------------------------------

= 64 ÷ 8.

= 8.

Answer 2

• Odd numbers are whole numbers.

• Odd numbers, when divided by 2, leave a remainder of 1.

• The smallest odd numbers is 1.

• Odd numbers from 1 to 15 are:

              1 , 3 , 5 , 7 , 9 , 11 , 13 , 15.

• Number of observations is 8

• The formulae for average is :  Sum of observations/Number of observations.

      ⇒  (1+3+5+7+9+11+13+15)/8.

     ⇒ 64/8

     ⇒  8.

The average of odd number up to 15​ is 8
