Answer:
The answer is 24
Explanation:
The given triomino follows as sequence that,
The upper no. × The right no. -The left no. = The middle no
As we can see this by analyzing the three triominoes
first triominoes
4 × 2 - 4 =4
second triominoes
6×1 - 5 = 1
third triominoes
3×4 -0 = 12
∵ Finding fourth triominoes
9×3 - 3 = 24
∴ The answer is 24
