Hi Carlos  thank you for that
What a good way to teach it (I am a primary teacher so generally only teach finding the nth term practically)
So is this right 7,11,15,19
It goes up in fours so it's 4n, 7  4 = 3 So the nth term is 4n + 3
Let me try another one 3, 8, 13, 18
It goes up in fives so it's 5n, 3  5 = 2 So the nth term is 5n  2
In my younger days I did A Level maths and Further Maths  I can't remember anyone giving me a system to find out the nth term  you just had to work it out.
I like the idea of linking this straight to graphs.

Richard  linking another tread (Bridging Units)  this would make a great bridging unit for transistion from Year 6 to Year 7]
