Step-by-step explanation:

To find : The average of 7 consecutive odd numbers if smallest of those numbers is denoted by 'a' ?

Solution :

The 7 consecutive odd numbers are 'a,a+2,a+4,a+6,a+8,a+10,a+12'

The average is the sum of observation divided by number of observation.

$A=\dfrac{a+a+2+a+4+a+6+a+8+a+10+a+12}{7}$

$A=\dfrac{7a+42}{7}$

$A=\dfrac{7(a+6)}{7}$

$A=a+6$

Therefore, the average of 7 consecutive odd numbers is a+6.
