Hi
 {{{(6*74 + 2m)/8 = 76}}}  
|Note: 6*74 is the total of the 1st 6 numbers and 2m the total for the 2 new numbers with a mean of m.
 {{{(6*74 + 2m)/8 = 76}}}  
 {{{(6*74 + 2m)= 8*76}}}  
      2m = 8*76 - 6*74
       2m = 608-444
       2m = 164
       m =  82
CHECKING our answer***
 {{{(6*74 + 164)/8 = (444+164)/8 = 608/8}}} =  76
Wish You the Best in your Studies.
