THX, JoLink

 

Here's a slightly  easier way

 

[ (1)(14)  + (2)(5)  + (3)(9)  + (4)(7)  + (5)(7)  + (6)(8)  ]

_____________________________________________  =

       14   +  5     +    9      +   7    +   7    +   8

 

 

[  14  + 10  + 27  +   28  +  35   +  48 ] 

_______________________________   =

                   50

 

162   / 50     ≈     3.24.......corrected   !!!!

( (1*14)+(2*5)+(3*9)+(4*7)+(5*7)+(6*8) ) / 50

( 14 + 10 + 27 + 28 + 35 + 48 ) / 50

= 3.24
