Recursive Formulas in Sequences

Mr. Allen introduces sequences, focusing on arithmetic sequences using blocks and geometric shapes. He explains how to derive recursive and explicit formulas, emphasizing the importance of common differences. The video demonstrates applying these formulas to find terms in a sequence, highlighting the practical use of arithmetic sequences in understanding patterns and shapes.
