Pattern 1 has 12 tiles, pattern 2 has 18, and pattern 3 has 30. What's the rule for the pattern?
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 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?
Where did the pic go?
Here are some ideas
