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.
