Rules for Number Patterns

The video tutorial explains how to identify rules in number patterns. It starts with an introduction to number patterns, followed by an analysis of two specific patterns: 1, 3, 7, 15, 31 and 80, 71, 62, 53, 44. The first pattern is explained as multiplying the previous number by 2 and adding 1, while the second pattern involves subtracting 9 from the previous number. The lesson aims to teach students how to identify and apply rules to find the next number in a sequence.

Explain how the number 71 is derived from 80 in the pattern 80, 71, 62, 53, 44.
