Finding and using the nth term of linear and quadratic sequences.

Author note — to cover

Fluency — nth terms of increasing and decreasing linear sequences, chosen from formulae with the term-to-term rule among the traps (4 questions).
Using the formula — finding a stated term and testing whether a number belongs to the sequence, answers exact (4 questions).
Quadratic — Higher questions halving the constant second difference and finishing the formula, with generated terms checked by substitution (4 questions).
