In this video, Lee Guffick works through Q13 and Q15 from Edexcel GCSE Maths Paper 2 (November 2024), covering direct proportion vs linear relationships, square-root proportionality and sketching graphs, plus quadratic sequences and a tricky term-to-term recurrence to find a later term. If you’re revising for Edexcel GCSE, this is ideal practice for spotting common traps and picking up marks quickly. ⏱️ TIMESTAMPS: 0:00 Intro 0:11 Q13a Table of values: why “linear” does not always mean “directly proportional” 1:53 Q13b W directly proportional to the square root of T 2:33 Finding the constant of proportionality k 3:12 Calculating W when T = 7.84 3:46 Sketching the square-root proportionality graph 4:27 Q15a Quadratic sequence: finding the nth term using second differences 7:41 Q15b Term-to-term rule: using u1 and u2 to find k 9:39 Generating u3 10:23 Finding u4 (final answer) 11:23 Wrap-up and next question preview ✏️ TOPICS COVERED: Direct proportion vs straight-line graphs (y = kx and passing through the origin) Proportionality with square roots (W proportional to square root of T), finding k, and sketching the curve Sequences: quadratic nth term (second differences) and a challenging recurrence to find u4 💯 EXAM TIPS: A straight line is not automatically direct proportion: direct proportion graphs must pass through the origin. “Proportional to” becomes an equation by introducing a constant k, then substitute a given pair of values to find k. For quadratic sequences: constant second difference means quadratic; if the second difference is 10 then the leading term is 5n squared. With term-to-term rules: use the given early terms to find unknown constants first, then generate terms step-by-step. 📚 ABOUT GUFFICK TUITION: Lee Guffick is a former Head of Mathematics and A-Level Examiner helping students achieve top grades and build the exam skills needed for the most competitive pathways. 📅 JOIN OUR PROGRAMME: → Personalised 1:1 tutoring: https://www.gufficktuition.com/tutoring → Small group classes: https://www.gufficktuition.com/group-... → Summer intensive courses: https://www.gufficktuition.com/tutoring 📱 CONNECT WITH US: → Instagram: @leeguffick → Website: https://www.gufficktuition.com → Email: lee@gufficktuition.com #GCSEMaths #EdexcelGCSE #MathsRevision #Sequences #DirectProportion #GuffickTuition
