the mean is basically the average of the numbers
we can calculate that by using this formula
[tex]m = \frac{sum \: of \: terms}{number \: of \: terms} [/tex]
first add both terms
[tex]61 + 68 = 129[/tex]
then divide the value 129 by number of terms
we know that the number of terms is two so
[tex] \frac{129}{2} [/tex]
so when we divide the answer is equal to
[tex]64.5[/tex]
hope that helps !
