2c. number sequences
Download as PPT, PDF0 likes73 views
The document presents several number sequences and asks the reader to determine the rule that generates each sequence and predict subsequent numbers. The first sequence increases by 1 each term. The second increases by 10 each term. The third decreases by 7 each term. Later sequences demonstrate rules such as doubling every term, increasing by 1.5 each term, and multiplying by 3 each term. The purpose is to practice identifying numeric patterns and rules.
