    Mathematics

    Including other sequences including where r is a surd

    AQAGCSE

    8300

    A multiplier can be irrational while the pattern stays beautifully simple. Master exact surd arithmetic, count the jumps correctly and turn unfamiliar Higher-tier sequences into clear, mark-worthy solutions.

    Mathematics

    Sequences: including quadratic sequences (Higher tier only)

    AQAGCSE

    8300

    A quadratic sequence hides a surprisingly simple rule: constant second differences reveal its n² component. Learn to rebuild the full nth term, handle negative and fractional coefficients, and turn membership questions into marks with clear algebra.
