We learned to find patterns. I learned how to do more simple to find the law of the problem. It can follow the formula. For example, 14, , , , 32, , , you can use (32-14)/3. Because there are three intervals between 14 and 32. And we learned analytic expressions, learned how to draw a form to find the answer. For example, 2+3=5. So the 2,5,8 interval is 3, and then add 3. Three decreases one is two. So the answer is 3X-1=y.
