Learn about understanding numerical patterns. Explore how to generate a second pattern from a given one by applying a rule, in this case, multiplying by 3 and adding 1. Then, graph the pairs of corresponding terms from both patterns on a coordinate plane. Created by Sal Khan.

- what is the pattern B supposed to graph?(2 votes)
The following table contains the first five terms of the given Pattern A. Generate Pattern B according to this rule. For every term of Pattern A-- so they give us the terms of Pattern A here-- multiply the term by 3 and add 1 to get the corresponding term of Pattern B. Then graph the pairs of corresponding terms. So for every term in Pattern A, we want to multiply by 3 and 1. So if we multiply 0 by 3, we get 0. And you add 1, you get 1. If you multiply 1 by 3, you get 3. And then you add 1, you get 4. 2 times 3 is 6, plus 1 is 7. 3 times 3 is 9, plus 1 is 10. Remember, we're just multiplying by 3 and adding 1. 4 times 3 is 12, plus 1 is 13. So those are the corresponding terms for Pattern B. And then they ask us to graph them. So let's try to graph these points. So when Pattern A is 0, Pattern B is 1. When Pattern A is 0-- so this is Pattern A equaling 0. That's our horizontal axis, the value of Pattern A-- Pattern B is the value of our vertical axis. Pattern B is 1. When Pattern A is 1, Pattern B is 4. So when Pattern A is 1, Pattern B is 4. Pattern B is on the vertical axis. When Pattern A is 2, Pattern B is 7. When Pattern A is 3, Pattern B is 10, so 3 in the horizontal direction. That's our Pattern A value. And our Pattern B value is 10. And then, finally, when Pattern A is 4, Pattern B is 13. Now, let's just look at these patterns. We see Pattern A is increasing by 1 each time, while Pattern B is increasing by it's-- well, Pattern A starts at 0 and increases by 1, while Pattern B starts at 1 and increases by 3, which makes complete sense. It makes sense that it starts at 1, because all of these, you multiply by 3 and add 1. So you start at 1. And then, the fact that we're multiplying by 3, that's what's leading to the distance between these points being 3. So let's check our answer to make sure we got this right, and we did.
