The answer is "8". The title of each "row" is the sum of it's members divided by the first number in the row.

(6 + 11 + 7)/6 = 24/6 = 4

(8 + 4 + 12)/8 = 24/8 = 3

(10 + 55 + 15)/10 = 80/10 = 8

(Another valid solution, submitted by Happy and yielding the same answer, is to multiply the terms of a row and use the left-most digit of the result.)
