Task goals
- Foundation: Complete first and second differences and use second difference = 2a to find a.
- Proficient: Use the first first-difference = 3a + b and the first term = a + b + c to find the complete rule y = ax^2 + bx + c.
- Excellence: Derive the three shortcuts, handle negative coefficients or a missing table entry, and verify a rule against another term.
