Answer 2

The average of the 10 numbers is 8.

Step-by-step explanation:

The sum of the first 5 numbers=50

The sum of the next 5 numbers=30

So total sum of the 10 numbers= 50+30

                                                   =80

Average of the 10 numbers=$\frac{Total Sum}{Number of terms}$

                                             $=\frac{80}{10}$

                                             $=8$

Hence the average of the 10 numbers is 8.
