Question

find the average of first ten odd number

Answer 1

Hi ,

Sum of first n odd numbers = n²

Sum of first ten odd numbers = 10²

= 100--( 1 )
Number of terms = n ---( 2 )

Average = ( 1 ) / ( 2 )

= 100 / 10

= 10

I hope this helps you.

Answer 2

The first 10 odd numbers are 1,3,5,7,9,11,13,15,17,19
Average = 1+3+5+7+9+11+13+15+17+19/10
              = 10
The average is 10
