Calculate with line entries

Hello all,

for the following file test.dat, I'm trying to do a simple calculation with the single line entries for every row.

content of test.dat:

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

The task is to calculate the line entries like that:

Code:

(7+10+13)/3 --> write result to row 16

(8+11+14)/3 --> write result to row 17

(9+12+15)/3 --> write result to row 18

Is there an easy way to do this with awk?
I tried

Code:

awk '{print ($7+$10+$13)/3}' test.dat >> check.dat

and it works.

Kind regards
