Sample: the first question, solved
What's the rule for 2, 4.5, 7, 9.5? What comes next?
📘 Worked solution
✓Add 2.5 each time; next is 12.
And one from the hard end
A pattern rule is "start at −4, and each term is the previous term multiplied by −2 and then increased by 1." Find the 5th term, and explain why this can't use a simple linear rule.
