To solve problems 9 and 10, let's analyze any pattern that could link the numbers in the circles with the number that should go in the box.

Problem 9

The numbers given are: 30, 31, 32, and 33.

One possible pattern:

• Check if adding or averaging these numbers could yield a meaningful result.

Let's try the average: $\frac{30 + 31 + 32 + 33}{4} = \frac{126}{4} = 31.5$ Since this isn’t an integer, another approach might be necessary.

Another possible pattern:

• Calculate the sum of all numbers. $30 + 31 + 32 + 33 = 126$ This could be a possible solution for the box in question 9.

Problem 10

The numbers given are: 32, 33, 35, and 37.

Trying similar methods as in Problem 9:

1. Average: $\frac{32 + 33 + 35 + 37}{4} = \frac{137}{4} = 34.25$ Again, this doesn’t give an integer.

2. Sum: $32 + 33 + 35 + 37 = 137$ This sum, 137, might be the answer for the box in question 10.

Solutions:

• Question 9: The answer in the box is likely 126.
• Question 10: The answer in the box is likely 137.
