Sequences & Patterns 6 | Cubic Sequence | First Method to find nth/general term formula

📘 Welcome to the next lesson in our Sequences and Patterns series for O Level, IGCSE, and GCSE Mathematics. In this video, we focus on finding the nth term formula of cubic sequences using the method of difference sequences. Before starting the cubic formula, we briefly recap linear and quadratic sequences to refresh the ideas of first, second, and third differences. In this lesson you will learn: A quick recap of linear sequences and first differences A quick recap of quadratic sequences and second differences What makes a sequence cubic How to identify cubic sequences using first, second, and third differences How to form the nth term for cubic sequences step by step in comparison with the formula of linear and quadratic sequence Complete simplification of the expression and revision of algebraic techniques Worked examples showing the complete process from differences to the final formula How cubic sequences are tested in O Level, IGCSE, and GCSE exam questions By the end of this lesson, you will understand a clear and reliable method to form the nth term of any cubic sequence.
