Pattern 1 has 12 tiles, pattern 2 has 18, and pattern 3 has 30. What's the rule for the pattern?

Hey! 

I'll first convert hese to co-ordinates: (1,12), (2,18), (3,30)

If you look at the pattern carefully you can see that you add 6 more to each y co-ordinate each time... the first time you add 6, the second time you add 12... and I imagine it continues like this!

Yeah, I saw that too! What I don't understand is how to write an equation in standard format for it..? All I could come up with for it was an equation based off of previous answers and it wasn't a y = mx + b equation, it was an equation for a sequence(?)...

I'm sorry, I can't find one... maybe someone else can?

I looked at desmos and I don't think that there is a standard format linear equation modeled by these points. Maybe they want an exponential function?

Ah, yeah, my friend just helped me figure it out right now! It's a quadratic equation/parabola and I just watched a video to finish it. The equation is y = 3x^2 - 3x + 12 if you were wondering. ^^
