Decimal Patterns
Repeating decimals continue without end with a repeating pattern. Some decimals continue without end, but do not have a repeating pattern. These decimals are called nonrepeating, nonterminating decimals. Although they continue without end, these decimals may have a pattern.
Examples of nonrepeating, nonterminating decimals with patterns:
5.121121112…
0.881882883…
Write r if the decimal is a repeating decimal and n if the decimal is a nonrepeating, nonterminating decimal.
1. 4.562222… 2. 6.1323323332… 3. 8.355355… 4. 0.230230023…
5. 10.7727227… 6. 4.121314… 7. 0.42818181… 8. 29.7053053…
9. 1.221221222… 10. 5.67167672… 11. 75.320333… 12. 4.121231234…
Identify the pattern in each nonrepeating, nonterminating decimal. Use the pattern to extend the decimal several places.
13. 0.010203… 14. 8.636336333…
15. 25.121231234… 16. 9.989796…
17. Write an example of a repeating decimal.
18. Write an example of a nonrepeating, nonterminating decimal with a pattern.
