Answer:
11 and 7
Step-by-step explanation:
To determine the answer, you must find the pattern in the first three numbers. It appears that each number is 4 less than the previous number, such as 15 is 4 less than 19 and 19 is 4 less than 23.
So, follwing this patern, subtract 4 from 15 to get the next number. 15-4=11
Next, subtract 4 from 11 to get the last number. 11-4=7
Hope this helped!!
