Question

a 2×2 grid (table) with four cells: top - left is 4, top - right is 16, bottom - left is 18, bottom - right is blank. horizontal and vertical lines frame the grid. a black circle with 3 is at the bottom left of the image.

Explanation:

Step1: Find the pattern in columns

First, look at the first column: 4 and 18. Wait, maybe rows? Wait, 4 and 16: 4×4 = 16? Wait, 18 and? Wait, maybe the sum of each row or column? Wait, 4 and 18: 4 + 14 = 18? No. Wait, 4 and 16: 4×4 = 16. Then 18×? Let's check the pattern. Wait, maybe the product of the digits? 4 is 4, 16: 1×6 = 6? No. Wait, 4 and 18: 4 + 18 = 22? 16 +? = 22? No. Wait, another approach: 4 and 16, 18 and x. Maybe 4/18 = 16/x? Cross multiply: 4x = 18×16. Then x = (18×16)/4.

Step2: Calculate x

Calculate 18×16 first: 18×16 = 288. Then divide by 4: 288/4 = 72. Wait, or maybe 4×4 = 16, 18×4 = 72? Yes, that makes sense. So the pattern is that the second number in each row is 4 times the first? Wait, 4×4 = 16, 18×4 = 72. Yes, that works.

Answer:

72
