Answer»

LET the numbers be x, x+2, x+4 and x+6 then:

Formula:

$(\eqalign{ & AVERAGE = {{SUM\ of\ elements} \over {number\ of\ elements}} \CR & Required\ average = {{x + x + 2 + x + 4 + x + 6} \over 4} \cr & \Rightarrow 29 = {{4x + 12} \over 4} \cr & \Rightarrow 29 = x + 3 \cr & \Rightarrow x = 26 \cr})$

Hence, the largest numbers = x+6 = 26 + 6 = 32
