Question

The first three terms of an arithmetic sequence are as follows.

Answer 1

11 and 7

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!!

Answer 2

the next two would be 11 and 7 because it goes down by 4 every time
