Sequences
There are two areas to look at with sequences.
The first is rules and the second is nth term
Rules
The rule of a sequence tells you how big each jump is so that you can keep the pattern going. This rule can be more than one instruction so it’s important to think of the size and type of jump.
Remember ascending means the pattern goes up and descending means it is going down. Don’t forget that descending and down both start with the same letter.
Some jumps are easy to spot (2, 4, 6, 8, 10, )
Some jumps are easy but you do a tiny bit of thinking first (1, 4, 7, 10, 13)
Some jumps are going to need some working out to solve them.

This sequence you can see the nubmbers go up so it is an ascending sequence.
To work out the rule you need to say what type and size of jump between each term.
So the rule for this picture is +4
(in your test if you just put 4 with no sign to say what you do with that number you will not get the mark. You HAVE to tell me what I do with the number in the rule).
