Sequences · Grade 7
In Grade 7 you learn: sequences from rules with letters.
A sequence is a list of numbers that follows a rule, like 3, 7, 11, 15, … Once you know the rule you can predict any term — the next one or the 100th — without writing them all out.
Key facts
- A term-to-term rule tells you how to get from one term to the next, e.g. “add 4” or “multiply by 2”.
- To find c, work out the “zero term”: the first term minus d.
