Warm Up Write a number in which no digit is repeated for each description. 1. 4-digit number divisible by 5 and 10. 2. 4-digit number divisible by 3 and 5. 3. 4-digit number divisible by 2, 3, and 6. Possible answer: 1,230 Possible answer: 1,245 Possible answer: 1,356
California Standards Preparation forAF2.0 Students analyze and use tables, graphs, and rules to solve problems involving rates and proportions.
3, 12, 48, , , , . . . 3 12 48 Additional Example 1A: Identifying and Extending Number Patterns Identify a possible pattern. Use your pattern to write the next three numbers. 4 4 4 4 4 A pattern is to multiply each number by 4 to get the next number. 48 4 = 192, 192 4 = 768, 768 4 = 3072 The next numbers will be 192, 768, and 3072.
7 12 17 Additional Example 1B: Identifying and Extending Number Patterns Identify a possible pattern. Use your pattern to write the next three numbers. 7, 12, 17, , , , . . . + 5 + 5 + 5 + 5 + 5 A pattern is to add 5 to each number to get the next number. 17 + 5 = 22, 22 + 5 = 27, 27 + 5 = 32 The next numbers will be 22, 27, and 32.
. Additional Example 2A: Identifying and Extending Geometric Patterns Identify a possible pattern. Use your pattern to draw the next three figures. A pattern is to rotate the purple triangle in a counterclockwise direction. The next three figures will be
Figure 1 Figure 2 Figure 3 Figure 5 Figure 4 Additional Example 3: Using Tables to Identify and Extend Patterns Make a table that shows the number of triangles in each figure. Tell how many triangles are in the seventh figure of a possible pattern. Use drawings to justify your answer.
Figure 6 Figure 7 Additional Example 3 Continued The table shows the numbers of triangles in each figure. A pattern is to add 2 triangles each time. 2 4 6 8 10 12 14 +2 +2 +2 +2 +2 +2 Figure 6 has 10 + 2 = 12 triangles Figure 7 has 12 + 2 = 14 triangles
45 41 37 Check It Out! Example 1B Identify a possible pattern. Use your pattern to write the next three numbers. 45, 41, 37, , , , . . . – 4 – 4 – 4 – 4 – 4 A pattern is to subtract 4 from each number to get the next number. 37 – 4 = 33, 33 – 4 = 29, 29 – 4 = 25 The next numbers will be 33, 29, and 25.
Check It Out! Example 2 Identify a possible pattern. Use your pattern to draw the next three figures. A pattern is three triangular objects that repeat, while alternating between orange and green. The next three figures will be .
