This table has equivalent ratios for x and y. What is the missing value?

x,2,5,7,9,
y,6,__,21,27

To find the missing value, we need to identify the pattern between the values of x and y.

Starting with the given values, we can see that when x doubles, y triples. So, to find the missing value, we can double the previous value of x, which is 5:

Missing value:
2 * 5 = 10

Therefore, the missing value is 10.
