What if Julie is thinking of an even number between 12 and 29with digits whose difference is 7? What is the number?
14, 16, 18, 20, 22, 24, 26, 28
Which of those numbers fits the description?
20
To find the number Julie is thinking of, we can follow these steps:
Step 1: Find the possible pairs of digits whose difference is 7.
Starting with the range of 12 to 29, we can create pairs of digits whose difference is 7:
12, 19
23
18
24
25
Step 2: Determine if any of the pairs create even numbers.
Among the pairs we found, we can see that 12, 18, and 24 are even numbers. Therefore, the possible options for Julie's even number are 12, 18, and 24.
Step 3: Verify if any of the numbers are within the given range (12-29).
Out of the possible options we found in Step 2, we can see that 12 and 18 are within the given range of 12-29.
Therefore, the number Julie is thinking of could be either 12 or 18.
