Into to finding nth term of quadratic sequences.
Starter = nth term of linear.
Ask students to generate quadratic sequences and find difference/second difference. See if they can find connection between second difference and coefficient of n^2. Algebraic proof that second difference = 2a.
Examples of finding nth term.
Included blank copy, and copy with my writing on (ie answers).
