Hi!
I will help you with joy!
Let's take a look at our pattern.
12, 11, 15, 14, _
Here, we subtract 1, then add 4, then subtract 1, then add 4.
Thus, the next number in the pattern will be 18.
12, 11, 15, 14, 18
The next number will be 17, and so on...
I hope it helps!
Ask me if you have any queries.
