Linear Functions have constant differences:

Term 1 2 3 4 5 ... nValue 4 7 10 13 16 ... 3n+1

Mathematical Models DO NOT have a constant difference BUT there is still a pattern!

First let's go through the reasoning of step 4....

What does the larger # in numerator represent?

What does the smaller # in the numerator represent?

What does the 2 in the denominator represent?

So based on this, what is the function rule for THIS problem?

Will this work for ANY problem involving points and # of segments from those points?

Let's try some pg. 115 # 1-9 oddDIAGRAMS are necessary....
