What is the "row heading" of the third row (marked with the question mark) in the table shown below?

    4 :  6, 11,  7
    3 :  8,  4, 12
    ? : 10, 55, 15

Explain the scheme used.

8 fits for another reason. If you add all three numbers, then divide by the first, you get the heading.

4 = (6 + 7 + 11) / 6
3 = (8 + 4 + 12) / 8
8 = (10 + 55 + 15) / 10
