How do you find the nth term rule for a linear equation?
1. Find the difference between each number in the sequence 2.This will be the cooefficient number of n 3.Then do (the coefficient number)x(n term, 1 is the best) and if that doesn't give you the correct no. then add or minus however much you need to

How do you find the nth term rule for a quadratic equation?
1. Find diff between terms until they are the same, half of this no. is coefficient to n^2, 2.Then use this rule so far on the no.term(1 is best) and find diff between sequence and no. you got 3.This is linear so just find nth term rule and add on

Find the nth term rule of the sequence 6,12,20,30,42
n^2+3n+2
4 of 5
Find the nth term rule of the sequence 3,6,11,18,27
n^2+2, if the linear sequence is the same number it is just that number, you don't have to find the nth term rule
