# What's the nth term for 7,10,13,16?

So first we need to find the term to term rule You can see that to get from 7 to 10 we add 3, to get from 10 to 13 we add 3, etc This becomes are coefficient of n (3n) Next we need to find out what we need to add to this number to get to the sequence 3*1+4= 7 3*2+4=10 So the nth term is 3n+4 where n is how far through the sequence you are
