The missing number(?) is "13".

Step-by-step explanation:

We have,

27 18  8

42  21  6

24  ?    4

The pattern follow in row-wise:

(Second term - Third term) × 3 - 3 = First term

27 = (18 - 8) × 3 - 3 = 10 × 3 - 3 = 30 - 3 = 27

42 = (21 - 6) × 3 - 3 = 15 × 3 - 3 = 45 - 3 = 42

Similarly,

24 = (? - 4) × 3 - 3 = ? × 3 - 12 - 13

⇒ 3? - 15 = 24

⇒ 3? = 24  + 15 =39

∴ Missing number(?) = 13

The missing number(?) is 13.
